Ok, I'm getting paranoid now!

Again last night I spent time replying to a post by avj99 and AGAIN this morning the whole thread was removed.
avj99 original post was asking about a system not supplied by TopLace.
I was telling him it was redundant to ask for advice & experiences, from customers using a forum, run by a company that doesn't even sell the type of hair system he's asking about.

Is this why it has been removed?
Are we not allowed to discuss other types of systems/products out there?

I'd like to know the ground rules please!
