I enabled user comments on this site several months ago, and on the whole I’ve been quite happy with the results. But I’ve had an increasing problem with comment spam, comments submitted to advertise products unrelated to my original postings. Many of these spam comments seem to be trying to leech off of my good Google page-rank, by causing my pages to link to theirs.
I’m fighting back technologically, but that’s a pain in the neck and will just lead the spammers to invent workarounds. So here’s a question for my lawyer readers: Is there anything I can do legally about this? Suppose, for instance, that I made people agree to simple Terms of Use before they posted a comment, and the Terms gave me some legal recourse against anybody who posted spam. It’s my site, and it seems to me that I should have the right to impose reasonable conditions on comment posters. I don’t know how effective this would be at actually stopping the spam, but it’s interesting to consider nonetheless.
