I receive between 25-50 spam comments on past postings each day in addition to the usual spam emails. From now on I will close all postings for comments 15 days after they were initially posted. If you really would like your comment posted please send me an email and I will put it up.
Unfortunately this action is needed to keep some of the obscene spam comments off the site, so I will try this and see how it works. The comment window may need to be further reduced again in the future depending on the results of this experiment.
Thanks for your continued site visits!
