New user DrAngelStella (Wikidot user 42 days, site member 8 hours ago), recently posted the same article three times out of bounds, all under the slot /scp-90000.
I PMed the user twice about this, the first after the initial deletion and the second after the second deletion. All three summary deletions were witnessed by gee, vivarium, and hex respectively.
Per the description they put in revision 0 posting, they do not appear to be checking their PMs.
Edit: they posted a fourth time. Staff convinced me not to summary immediately and to instead edit their article to explain to the author directly that they are posting out of bounds, as they continue to not read their PMs. Article was eventually summaried as well.
