I haven't for the most part. Although when joining an AEN type situation I would read everything to make sure I got their rules straight on how many pictures a gallery needed, how many banners you were allowed etc.

But we should be reading (and trying to understand this stuff). I've just dealt with a webmaster who put his sites on a freehost. The freehost then took the code associated with his MANcheck enter button and altered it so it created a 404 error type situation, and then the free host was offering the surfer their stuff. The webmaster couldn't see this problem because I guess there was some kind of a filter preventing traffic from within his country or from his IP address from seeing this.

Essentially, they were stealing almost all of his traffic. I had to point out to him that it states in the free hosts TOS that they have the right to alter your pages at any time and they don't have to send the traffic where you want it to go. The only thing they HAVE to do is provide him with 50 mb of web space, and even that's up for altering at any time they see fit.

So, while this isn't related to sponsors per se, this does show that if you don't read a TOS, you could be in for an interesting ride and you could be losing a lot of traffic and money.

Cheers,
