The spammers cometh
So, Mark noticed on Friday that the spammers have found redefine, and as a result, several of our blogs have been "crapflooded" -- i.e., the comments to our posts were filled with spam. Rushabh suggested that I install MT-Blacklist, which I did today before going into the city. So far, it has been useful in de-spamming my blog (deleting comments in the MT user interface is painful), but the jury is still out. The problem with any sort of blacklist is that you have to keep the definition file updated (which doesn't appear to be easy to automate), you can get false-positives, and the spammers can always be "one step ahead". Ultimately, I think that I may either just disable comments, or move to a forced-registration system, like what Carl is using now.
