I am going to try it
I am going to turn on comments that don’t have any HTML code in them, will go live, I will do a trial run for the next week or so. If i find that I get to many spam posts that are going live, I will shut down the test, if things go well I will leave it that way.
I have the following two methods going right now, 1) any posts older then 90 days will not permite comments to be posted to the, and 2) I have added a word filter, I have filtered out some of the words that most spam comments share in common. Lets see how this goes.
