I hate twitter, so I hope so. I've been trolled good and proper on Twitter. It's a homeopath thing in part [I'm a homeopath]. If you use the #homeopath tag on Twitter you get the skeptics welcome wagon and they are fierce, well paid [I suspect, or at least zealous] and they have automated conversations they throw at you far faster than anyone can type. They set up troll rings and all come out of the woodwork at once [up to 20 of them I had]. They then try to intimidate you with nasty pages about you on their personal websites [there are a few on me]. It was a painful process. I was pre-warned and it was still tough really. I stopped tweeting. I don't like that element of Twitter at all. It's a bit prone to road rage like behaviour.
On the brighter side, many folks on the #homeopathy hashtag came out to tell me who to block and to help me out, because they know it happens all the time. They were very kind and supportive, but you know ... it drives you away to deal with one after another, after another troll.
