I’m not really sure, I have a few ideas but nothing that is a direct alternative to Burggit. There are two things I use Burggit for and that’s to view loli hentai and to occasionally talk about hentai games. There are a few websites I know of for viewing loli hentai but for talking about games, the only website I currently know of is F95zone and I have an account there but outside of using it to download games, I’ve only ever commented once and I’ve never made an actual post there before. I’m sure that F95zone would be fine, I’d just have to get used to how different the platform is.
I have read F95zone’s rules and I have seen people complain about how vague rule 7 is. While I have been using ATFBooru for a while now, I’ve never had an account there and this is the first time I’m hearing about lewdcorner. I’ll check them out.
