Is it smart to post comments in this blog?

Quick answer: no


Long answer: probably not


The admin at GOM will at some point be aware of this blog and they could use rule 7 to ban you saying you libelled them.  Even if you didn't.

Rule 7 has history, I wrote it before I became a mod

7. Accounts will be summarily closed, where used to promote or defame other web sites, where moderators or administrators of this forum are libeled or defamed or where those accounts are identifiable as being used by those who have committed such libel or defamation.

It all harks back to the days of the now deceased GC site where several were posting all sorts of nasty content about Steve and Dawn Lewis Allen and then crying foul when their GOM accounts got closed.  So I suggested there was a clear rule. 

I'm not saying don't post a comment but better safe than sorry
