Didn't Patreon update their ToS a while ago? I've seen a bunch of games getting in trouble with Patreon lately, so maybe it was just L&P's turn. Saying that because you question as to why AWAM was suddenly a problem.
Another thing I find confusing.. You say L&P can't expect a message from Patreon about the link, but then you also say the review before his ban was specifically about that link. So he must have gotten the message you say L&P can't expect from Patreon during their first rodeo, otherwise how would he know the link on F95 was the problem?
AWAM is being shared on a bunch of pirate websites, and there's links to his Patreon page on all of them. The game itself is linked to his Patreon page aswell.
Man, it's really annoying that I've missed out on all the "fun" when apparently DM's and whatnot had been posted here. Which is also weird that they've all been deleted for some reason. I've still not seen any DM or screenshot from L&P and Patreon that prove the first review was specifically about the link on F95. It's just what people have been saying, and I hate having to blindly believe what's said by random people. The only thing I've seen is an E-mail after his perma ban that clearly shows how Patreon doesn't like incest and shota and the screenshot from L&P's Discord provided by
PietruccioTheHilander where L&P "assumes" the ban happened because of a link.
