The only creepy comments I can remember off the top of my head was when I introduced Wen:
... and some of my readers were getting all excited over her thighs (one of them specifically said "she could crush my head with her legs and I would die happy") - but that was the only time, and it was definitely mostly joking around; those readers are frequent commenters, and are otherwise not creepy.
I'm just... really, really happy that Tapastic is overall such a friendly and positive place, because I'm drawing a comic about a grown man taking care of a small girl, and this is the internet. Rule 34 is a rule for a reason, and I really, really don't want Masahiro and Akane Rule 34'd.
