If a host is moving your post around or freezing a thread or something.. for no good reason.. then yup I get it. But if you are saying hosts shouldn't be able to comment ... Of course they should. They are paying customers as well.
I wish hosts would merge threads down there more, as every time somebody posts a similar thread that waters down somebody else's vote. They only seem to merge my threads for some reason.
With so many hosts available I don't see much work going on. If they aren't able to perform host duties effectively they should give it up and let somebody else have a go.
Take an example from me.
