About this request: you could ask one of the admins to delete it, if you really wanted to. You can figure out who's been on wiki recently by looking at this log.
On your real question, I recommend using a new/different password on the test wikis, including the Beta Cluster and the temporary PatchDemo wikis. While these are official WMF-hosted sites and subject to the same privacy policies that you would normally expect, there's always a small chance of a new security bug.
First, I won't bother with deleting the question at all, I will instead of spending hours figuring it out, let the experts like you deal with it in seconds. Thank you for saying it, thought.
I admire that you (tried) to answer my question, given the low effort I put into it, and its rant/anger/unpolite tone. I edit wikipedia minor edits here and there, but I, like most 99.99% of normal users, am intimidated by the difficulty of the impenetrable rules, customs, systems. This site, wikipedia, looks like a dinosaur, big, old, and complex.
I'm writing a lot because I'm relaxing of work. I wish you the best, thank you, I'll try your suggestions!
