@astolfor , Members can delete their own posts within a 30 minute window (the same for editing). What it takes for one to have someone else's post deleted is to complain (whine, cry, etc) to the mods by having it flagged and it usually is deleted without any real review.
I've had posts reinstated by contacting the mods to have them take a good look at the posts and how they fit it with the context of the thread and not differ with others. Lately, I've given up on it due to the effort it takes and I don't want to have the mods spend all their time on something so small a matter, so sometimes I post what I did, above. The offenders know it and as a result, those in the thread can appreciate it.
All the best,
Nonoise
