Hey Sergio, I'm afraid removing account and all his posts will ruin integrity of discussions involved and in general will deprive audience of any knowledge contained in such posts, which is a really bad thing for community. Trust me on that, I am currently browsing a forum where one person freaked out at 2017 and removed all his posts starting from 2008 - it looks extremely ugly and make me mad to think about all the insights I have missed only because I didn't browse that thread 3 years ago.
If you are worried about your posts being done in the wrong place, don't hesitate to report such posts, it doesn't mean auto-ban or anything, it will just draw our attention to a place where something should be fixed, and I'm sure you aren't mistaken often enough to put a strain on us In fact, I already saw one of your :deleted: posts, but decided not to remove it without your request.
