Please refrain from the following in your comments:
1. Racism, sexism, ablism, transphobia, etc etc. This includes stereotypes about groups of people, and use of slurs.
2. Body shaming comments. While I understand that people are reacting to depictions of women in comics, the issue is about how the industry/artist/etc choose to present, draw and depict women, and that they often portray women as only having certain body features. Don’t make comments like “no woman has breasts the size of her head”, “real women have curves”, or that women without big breasts “look like a 12 year old boy.”
3. Gender essentialism. This is not saying there are NO general physical differences between cis men and cis women, but relates to statements about how muscular women look like men because only men can have big muscles, or that women all have thick lips, or etc…
4. Personal attacks about redrawers, artists, or other commenters. Criticism, even harsh criticism of the artist/redrawer is not a problem, but not “you must be jealous and fat” or “that artist must be a loser who jerks off in his basement.” There’s sometimes a grey area about what constitutes a “personal attack”, and I trust Ceridwen to make the decision in those situations.
Ignoring these guidelines may lead to a warning from Ceridwen. Repeated warnings of the same type may lead to a ban. She has leeway to ban outright if she feels the commenter is posting in bad faith (i.e. trolling), or to warn multiple times if she feels these are honest mistakes.
Update February 4th 2013: Sock puppeting (creating alternate names/accounts in order to pretend to be different people) is an automatic ban.
