I posted this originally over on my personal weblog, but thought it was important enough to post here (where it may get more coverage)...
Potential Issue: Tag Spam
Thought: let's say some spammer get's it in their mind to fill a webpage with thousands of Technorati Tag links. They then ping Technorati. Technorati indexes the page. What happens?
Expand the thought... what if the spammer takes hundreds of pages, fills them with thousands of tag links generated automatically from dictionary word lists then pings Technorati? What if a whole bunch of spammers start doing this?
I wonder if Technorati's infrastructure is designed to withstand such an attack? Tag Spam could potentially kill the tagging revolution if given the chance to fester. Google's nofollow wouldn't solve the problem because (I would think) you'd want to be able to index tag pages.
Update: I'm not the only one thinking about this: tag spam
