Chapters behind paywalls (coin systems, patreons) and warnings

[kn4ll]

Could we have something like the warning for pornography for groups and releases by groups that have paywalls? Like Nikatoons, Asmotoons, Art Lapsa, KDT Scans, and Rithar_Scans? And I guess good old Galaxy Degen Scans and Soseki Scans. I don't necessarily think you need to blacklist the groups, but people should be warned that they're no good groups that are in it for the money, and that people shouldn't pay for chapters. Preferably something like "if you've bought chapters from these groups, you have been scammed".

Maybe add something like "Do not pay for piracy" or "Paying for piracy is a scam". I dunno.
