We had no comments to our posts for MONTHS and now almost daily we get junk that I have to go and "moderate" - which means of course, deleting it. The websites these spam posts seem to emanate from contain incomprehensible babble and the comments are come-ons for ring tones, or a few words, meaningless dribble. I'd like to block them but don't know if that's possible; I go in and mark them as "spam" but there is no indication of what that does. What's the point? Can I block this crap and if so how? Anyone know if its from one source - many of the weird websites have "massage' or "ring tone" in them and are just bizarre word salad. I'm new here and pretty unfamiliar with how things work so be gentle? Thank you!
