He/she probably left after the "warm welcome" everyone gave him. What is wrong with giving a new member the benefit of the doubt? I would rather have 50 trolls on the forum then have one legitimate new member ran out of town by a torch carrying mob. Trolls can be banned but how do you get someone back that right out of the chute was crapped on?
If given enough rope a BS'er will hang themselves.
If OTB was a troll nobody has been harmed or hurt in any way. If they were legite then I don't blame him/her for going elswhere.
I think this post is spot on - the label troll is tossed around far too much, just because someone posts something that is unusual or uses a term that may not be used regularly "IN YOUR AREA' this is no proof at all that someone is a troll and posting stupid pictures and definitions of trolls just because you dont like what has been said is pathetic.
Trolls usually show themselves up eventually but there is no way you can decide for certain after someone has made 4 posts, if you dont believe them fine dont say anything, but there is no need to try and run them off the forum or demand that they explain themselves. I have often heard people use the term 'in the ministry'
