Well i have leak alot of game before and got blocked too. It dosent realy help blocking becasue all you need is a new profile and bankcard. If you need to go somewhere like discord for a password you can just use a vpn if you are blocked. Devs schould think twice before blocking someone, because it can lead too grudge from the customere and the next time they will leak it faster.
In your case i think you are justified.
Blocking to prevent piracy doesn't really work longterm, as you said, because the security measures that could be effective in hindering block evasion would seriously negatively affect subscription (for example tying accounts to a photo ID, which has a huge chilling effect - which is why anti-porn crusaders are pushing the various age verification laws).
And thus yeah, they may try again next update, and will probably be successful (on the patreon side, wouldn't be surprised if F95 measures are refined in response and would catch them next time), but:
This isn't really about preventing piracy, but making clear that tampering with the files will not be tolerated.
Just because you can't ensure perfect security doesn't mean you don't 86 someone when they endanger people.
