Glad the post helped but it looks like I misunderstood a few things.
You don't have to declare income if it's below a certain threshold. Or more accurately, you don't have to pay taxes on it, as long as it is a donation you received.
Platforms masquerading as tipjars do not count as donations or charities, but as services, and some of them exploit many legal loopholes. The only applicable tax technically is if a product (physical or digital) is delivered to the end customer. VAT, GST and (remind me what the third one is?) have clear limitations on their implementation. Make sure you check with an accountant, this is the case for both backers and creators, and if no one blows the whistle, this will go unnoticed. The government won't even know what happened. OnlyFans is based in London, UK, and the UK isn't exactly known for its permissiveness.
If you really wanted to get raped by Patreon (located in San Francisco, California, US), simply state you live in Hungary while also supporting a content creator who also claims to live in Hungary. Also ensure the creator does not create anything, so you are effectively using the service to back them and nothing more. Check how much money gets taken from yourself and from the creator. On top of the (legal) fee, you'll have to pay: bank fees (legal, only if you use a credit/debit card and only if your bank charges for it), transaction fees (also legal, depending on said transaction), as well as potential taxes you do NOT have to pay because they are entirely illegal. Unless your physical place clearly states that these do apply, and you have evidence of it going to the government (you can file anonymous requests for transparency, for free, to have a company investigated, directly through your government, again depending on the country, to ensure the government did perceive taxes).
Now let's get back to where I misunderstood.
If you don't want to pay any tax at all but still earn money, you will have to use donations. Commissions work this way as long as you do not exceed a certain threshold (country-dependent) and you do NOT use any payment provider (as you would pay a fee) or payment method that involves any kind of fee (cryptocurrencies also have fees - see mining fees - and they are getting closely monitored now that goverments hold a share and made them illegal for obvious reasons, not just for their own benefit).
You can also use platforms like Fantia running limited campaigns for new creators at a 0% fee (the legal creator-to-platform fee for using it as a service) and then opt out.
Now, I'm not trying to shill the government, but I absolutely loathe abuse of welfare state plans and relief (see COVID abuse, see Medicaid abuse) while clearly shady companies are trying to get away with it. Not even Google or Apple does this on Patreon's scale, as while they do perform some tax avoidance, it is legal. Tax evasion, or rather deliberate misuse of taxes that clearly don't apply, registers as a deliberate and malicious act of tax fraud on a large scale. Furthermore, encouraging third-parties (their own customers) to follow this scheme while violating their own terms of service also causes even more potential legal damage to the company. Unless they are exploiting a massive legal loophole on the international scale, there's no way out of this one, but an international commission has to sue first.
Sen. Chuck Schumer and the IST lost a few suits (back in 2012, and another one in 2016 if memory serves right) against Apple Inc. for monopoly abuse. Now this here isn't monopoly abuse. Don't send the IRS against Patreon. Simply have your country investigate and alert the IST, that's their job. There is no need to sue on your side, and you will not get damages. What you want is to simply have them out of the picture for running a criminal business scheme.
As this post will very likely get removed from public view (wouldn't exactly be surprised if F95 went shit do what now and tried to wipe the account when everything's already widespread anyway), I'd still like to add that F95 apparently tries its best to cover up what's going on with the more infamous creators running a full-scale Ponzi scheme. This is already publicly known information and has been reported a long time ago (back when it started and when evidence was collected, then provided to the proper authorities by enough parties). F95 sure as hell won't get involved in this as it is a piracy website (it does, however, state that it does not condone resharing of content as a disclaimer, while also conveniently using Patreon as the main platform while there are many alternatives, some of which are quite greedy, but at least not complete criminals trying to look like saints, just like Jacob Grady and On Takahashi, but this time, internationally).
tl;tl;dr: If donations aren't an option, get an accountant, and make sure you don't fall for obvious or less obvious scam schemes. You really don't want to get involved with something that may also end up destroying your entire life if you somehow make them 'look bad' (oh the irony), which you can provide as a counter-argument on how a completely fraudulent company is trying its best to look good on the surface, before wiping all of the posts mentioning 'Patreon' from all of your social network accounts you were dense enough to link to it (that includes F95, by the way, so to anyone who linked it: you did some research first, yes?)
That is all. If a moderator or staff member decides to 'delete' this post (emphasis on 'delete'), I respect their decision as I have said what I wanted to say and I am aware this may rile up certain people, especially if there is lobbying involved, and apologize for wasting their time.
And to the OP, don't feel too bad if something happens, you did nothing wrong, you asked a question and this poster jumped the shark to blow the whistle quite hard this time. This is just an account on the Internet. I have more than enough health issues in real life to concern myself with Internet stuff.
Remember to spread the word, and don't spread the word as fake news. Bring evidence with it, objective and irrefutable evidence, which you have relayed to the authorities beforehand. Boycott isn't something you do by brainwashing, it's something you do with evidence, by having people realize by themselves they're getting raped or that they're just idiots and you can't cure stupidity, so they won't boycott anyway.
