rzrforums question from a new member

Hello, and thanks so much in advance for this forum, the wealth of knowledge within, and any time/responses you can provide to my question.

I’m new to this forum and found it after researching the Pitster Pro product line, when I wasn’t able to locate a nice used RZR 170 in our area, and couldn’t afford a new one. After having been persuaded by Pitster via phone/email to purchase one of their products, and recently reading a request for feedback on their products in a thread within rzrforums, I responded. After posting my comments tonight on the one we purchased, my posts were removed (by Pitster I’m sure, as I see that they’ve also modified other users’ comments in other threads). Is this practice of removing/modifying other users’ posts accepted on the rzrforums? I’m a member of numerous different other forums and have never seen anything like that happen before.

Thanks so much for your time
