Not long ago I posted about a hack that allowed TypePad users to ban specific words in comments or trackbacks by entering them in the field for banning IP addresses. I cautioned against using it at the time because it had an unresolved issueâ€” the words were not specific enough. Banning the word “the” would also ban “theater,” “theremin,” and so on. But that just changed.
TypePad has updated their spam protection settings to make this a real feature with an improved interface allowing words to be banned safely. Now, I’m not one to ban profanity for exampleâ€¦ and there are a lot of words that show up in spam that also have legitimate uses (like MP3 for example). But there’s a much more powerful, hidden side to this new word banning feature. It allows you to ban URLs!
If I can ban specific URLS, I can prevent the vast bulk of spam from ever reaching my blog. This has me pretty excited. Banning IP addresses doesn’t do much to stop the spread of spamâ€¦ IP addresses can be generated on the fly. I’ve often had dozens of spam comments or trackbacks from the same website that use different names, IPs and contents. The one thing they all share in common is the URL. So, while I wouldn’t suggest banning the word “online,” banning “www.spaces.msn.com/onlinecasinosgambling” is a winner.
I’ve actually been saving a few spam trackbacks all week while I waited for this to go live, just so I could have the pleasure of banning them officially. Heh. It’s too soon to say for sure, but I really think this will be a much more effective way to block spam than CAPTCHAs or IP banning. In fact, I’m going to remove the CAPTCHA requirement from my comments now that this has launched. I hate having to fill them in myself in order to reply to comments.
Adding a word to the ban list will block any comments or TrackBacks which contain that word. Word banning will ban instances of the word regardless of whether it contains upper or lower case characters.
does not mention URLs specifically, but as you can see, topping my list is the casino spammer that last hit my blog this week. And so long as you ban the URL as one word, you won’t be banning parts of it such as www.
Congrats to the Design Team for this one! I think it’s gonna make a big difference in keeping comments and trackbacks clean of spam.
