backtagging / backdating: no problem at all. if a thread seems like it won't go much of anywhere or is getting difficult to keep inspiration for, i may drop it, but you shall be notified in such a case.
threadhopping: generally, i'd prefer if you ask first, especially with full-on logs. i tend to be chill in network posts, though, as long as they're public.
fourth-walling: maybe, depending on the situation. please ask first.
canon puncture: sorry, but definitely not, unless it's something that happens in canon (i.e. mario and sonic canon puncturing).
sensitive subjects: go for them. i have absolutely no triggers.
munsterbating: only if absolutely, positively, without a shadow of a doubt necessary.
