Well that subscribe to comments function proves to be another extra job. My anti-spam measures might block spam comments, but not the spam subscriptions to comments. Not that these are of any use, but an automatic spam bot doesn’t care about that of course. Since I don’t expect ongoing discussions about music or filmreviews or newsitems, I disabled the plugin in these parts. If in the bookreviews and articles sections things remain silent, I might just as well get rid of it there as well.
