Ok, so one report on a non English speaking forum in this post:
https://www.flyertalk.com/forum/28942714-post2.html
So three reports of account closure for pooling issues.

I read Jimgotkp's post about problems with pooling as one that he wasn't able to complete a pooling request. He says there has been no account closure. Pooling has had problems since it started with failed pooling requests, there are a number of reports like Jimgotkp's in the general pooling/new perks thread.
