Actually, I believe it's the TB who determines what goes into forums when they are created. Suddenly, those threads which are deemed to be un-TSA friendly or particularly contentious, are being sent to Omni P/R (and have nothing to do with P or R). Some of them are started or contributed to by people who can't see Omni.
If threads of this nature are not wanted in TS&S, then why put them in Omni? It's just moving the bad behavior from one forum to another.
Please not that 2 of the Omni mods are also TS&S mods, and it's they who do the moving [that's not a complaint or dig]
I've been reading over there, and quite honestly, I have never seen such contentious threads anywhere else on FT - including Omni P/R. Some of these people only post in TS&S and they gripe over and over about the same thing. A few are a sandwich short of a picnic (one landed in Omni

)
If those types of posts are to be discouraged, IMHO they should be locked - not moved.
FWIW -I posted similar in Omni and it was locked because I was discussing moderation and I was directed to the community director. I would prefer not to bother her with something like this because I believe it's one of the roles of TB.
