It may be since my comic strip is so new, the imbalance is more dramatic in my logs than for other, more established sites. That is, views of my comics over here are completely overwhelming what little traffic I've got going on over there. ;)
Some other sites may simply have not noticed. Nobody has time to follow back every referrer in their logs to see what's going on. If you've been doing this for a while, you've been lucky; syndicates and networks *do* send out these lawyerly letters when alerted to other sites linking their graphics. That's probably not the best way for it to be handled, but it does happen.
But thanks, again. As I said, I *do* need the exposure, at the same time. I can see how it might have looked like I was complaining in the first post, but I felt I had to mention the other posts, anyway, so this wouldn't look so much like spam. That's the Catch-22... you'd like to share, but one man's sharing is another man's spam. :)
