I have posted you few screenshots few comments above. You might have missed it.
The user was reposting previous posts. Deleted old posts and replaced them with fallacious "error" message in an attempt to cover up the recycling. Probably thought that deleting it would make it impossible to search for.
The same activity has been done many times by many different users who tried to deceive in the same way. It is a very predictable activity that we have seen many probably hundreds of times.
