Search is probably half broken again, your posts will still be there if you can find them through alternative means (e.g. google search). I did find this post on a sales thread from last year if it helps: https://www.mpgh.net/forum/showthrea...1#post15383462
Unfortunately the issue with IM is still the same. Messages can be viewed again if they re-add you though, so they aren't completely lost. Dave is also able to pull the logs if necessary, but it's usually only done for scam reports and stuff like that.
