User Dr Fabian Leweck (wikidot user since Sep 6 2021) spammed six pages in less than five minutes an hour1 earlier today.
I emergency revoked and sent a PM; the delay in a thread was due to me doing so while preparing to go to work, so I didn't ensure somebody else would have put the thread up.
PM was sent. Present staff opted to allow all the articles to remain up, as several were falling at an average and reasonable speed and at least one at that time was actually in the positives.
In my PM I requested the user slow down so as to properly get feedback for their articles. Ideally this advice is followed when they return.
