I think it's understandable if he wants to distance wapchan from NSFW stuff, especially if he is planning to associate his IRL identity with the site for some reason. So don't pick on ranchan for this please.

...Though I find trying to keep a site about old anime strictly SFW a bit odd, considering all the fan service in the shows

He should probably have also notified other sites' admins about it. I am online enough to quickly notice it by myself, but I see the other site that was linked with wapchan is still linking back to them...
