Hello all,
Unfortunately I found a bug in Education program Namespace (I found it in ar.wiki and I think it's a global bug).
**Clarification:**
I'll talk about [[https://ar.wikipedia.org/w/index.php?title=%D8%AE%D8%A7%D8%B5:%D8%B3%D8%AC%D9%84&page=%D9%88%D8%B1%D9%83+%D9%85%D9%86%D8%B2%D8%A7%D8%AD+%D9%84%D9%84%D8%AE%D8%A7%D8%B1%D8%AC|this example]]
user:X = user:حل إشكال
15:56 - User X added himself as a reviewer for [[https://ar.wikipedia.org/wiki/%D9%88%D8%B1%D9%83_%D9%85%D9%86%D8%B2%D8%A7%D8%AD_%D9%84%D9%84%D8%AE%D8%A7%D8%B1%D8%AC| this article]] in [[https://ar.wikipedia.org/wiki/%D8%A8%D8%B1%D9%86%D8%A7%D9%85%D8%AC_%D8%A7%D9%84%D8%AA%D8%B9%D9%84%D9%8A%D9%85:%D8%A7%D9%84%D8%AC%D8%A7%D9%85%D8%B9%D8%A9_%D8%A7%D9%84%D9%87%D8%A7%D8%B4%D9%85%D9%8A%D8%A9/%D8%A3%D8%AF%D9%88%D9%8A%D8%A9_%D8%A8%D8%AF%D9%88%D9%86_%D9%88%D8%B5%D9%81%D8%A9_(%D8%A7%D9%84%D8%A3%D9%88%D9%84)|this page]] (Education program Namespace).
16:03 - User Z remove User X from the previous page (Education program Namespace).
But it appear [[https://ar.wikipedia.org/w/index.php?title=%D8%AE%D8%A7%D8%B5:%D8%B3%D8%AC%D9%84&page=%D9%88%D8%B1%D9%83+%D9%85%D9%86%D8%B2%D8%A7%D8%AD+%D9%84%D9%84%D8%AE%D8%A7%D8%B1%D8%AC|here]] and everywhere that User X remove himself.
I n real this what happened with us in ar.wiki that User X made a mistakes so we run CU tool on his account, but due to the previous situation CU tool appear User Z identical to User X (in IPs + user agents and everything), so we block User X and User Z (note that User Z is a sysop in ar.wiki).
After advanced search I tried many thing, finally I found this problem.
I know all people in Education program now using [[https://outreachdashboard.wmflabs.org/|The Dashboard]] but our sysop [[https://ar.wikipedia.org/wiki/%D9%85%D8%B3%D8%AA%D8%AE%D8%AF%D9%85:%D9%85%D8%B5%D8%B9%D8%A8|User مصعب]] (=User Z) still using Education program Namespace until now in Education program in [[https://en.wikipedia.org/wiki/Hashemite_University|Hashemite University]].
Thanks all
