All I can say for my opinion is that as far as I've seen the creepy shit definitely outweighs the silly shit. I dunno shit about Nexusmod or the moderator drama there, but while there might be some decent stuff on Loverslab finding that stuff is like looking through dog shit for a penny the dog swallowed. Not worth it in my opinion. As for the loli mod, while it may not be on the actual site people were commenting on it and asking about it in more than one thread.
If you've got any of that funny mod stuff stashed away somewhere, I'd be more than happy to look at it if you post it somewhere. For myself, I really can't be bothered to slog through that place again.
