Sponsors are great, they pay for the site usage and stuff. Yaay for the sponsors, thanks for paying for things. Yaay. But what is not great is posting about one thing and hearing about a totally different product that has no bearing on your post. Sure, I can skip right by it and ignore it. The first 100 times. Then after that, I'm gonna complain about it. When you become a PITA, you negate any positive influence you might have had in being a sponsor. And I am not even going to think about buying your product. Same as telemarketers. Honestly, it's not a huge problem yet. But those that perpetrate this should be made aware of it, before it becomes a huge problem. And I have no problem speaking my mind about it, no matter how free the site is.
