Grrr


I just manually cleared out about a hundred comments out of DA! by spam linkers who are trying to increase their search engine placement to the detriment of my own. I've now implemented some more error checking in the comment script to block any entries that include "http:" (a sign they're trying to add links; only 1 out of 300 legit entries actually used http:) and a few things that were obviously spam (a lot of the entries had the comment "Add" and "Add Entry" which was either the comment script adding the submit button value in the comment field or the spammer entering the nearest text on the page into the comments field).
Another thing I did not add was an IP check, because the script already collects the IP and they're generally different in the spammers' cases.
If anyone knows of a script (PHP preferably) that would help decrease the rate of these incidences, I'd love to hear about it.

I'm not sure of a script that you can install and use to decrease spamming in comments...but I've heard of a technique where you require users to preview their comments before actually submitting them. Most spammers don't go through the second step, so spam gets lost in transition.
