Nothing has been removed recently – and it is worth noting nothing is ‘accepted’ before posting, we do not have any pre-moderation, let alone ability to do so inside milliseconds it takes to post.
Edit: There are two ‘pending’ threads – one now visible at https://www.wrexham.com/forums/topic/council-report-ignores-problems-highlighted-by-estyn never had that before and all other threads/posts seem fine. There is nothing different about your account either from anyone elses. No idea yet what has happened there!
Edit 2: It appears the issue is new threads with links in, and the software is pulling that as a possible spammer. This appears to be a new thing as previous new threads have been fine with a link in them.
