This site allows for piracy so I don't think the admins will have a problem with it. Patreon, on the other hand, might take down an account if the account is reported for copyright infringement or some other similar legal issue.
More importantly, the person running the patreon may also be vulnerable to legal (and possibly criminal) consequences. Online revenue is usually pretty easy to trace so you might just paint a big target on your back by trying to cash in on piracy. I'm not a lawyer so I don't know for sure but it makes sense that there would be laws against this kind of thing.
