While a big part of me agrees with you, I'm also forced to admit that it's a novel twist on an old question, and the OP hasn't mentioned any names at any point so kudos to him/her. No fingers were pointed and the evidence as much as it can be called that was presented with a question mark as to the possibility that it could be the Stig. The only names mentioned have been from more established users and not from the OP.
I think it's a nicely restrained effort for a new member compared to the "4 posts and several red blobs" candidates we've seen rather too much of in the specific episode discussion threads of late. As a relative newcomer myself still learning the finer nuances of life on here I for one would suggest that you old hands on this occasion cut the OP a little slack. I've made mistakes and I'm not afraid to admit it but in the main I've been made to feel welcome and I have to say I reckon from most of the replies on this thread the OP will probably be feeling the same.
Heads off to the woods to hug a couple of trees, uncertain whether current therapy is really working
