I've seen T write mostly good English on another site.

He can do it if he takes the time.

Well yes, like you say, a bit of that and some copy&paste from somewhere else. I could write a post now, decide basically what I'd like to say, then I could find a sentence that you wrote, another one from, Beth, another from SB..and so on. It does take a lot of work though. You have to be a dedicated linguist hahaha! Most of the boring posts written on other sides can be cobbled together in such a fashion. The thing is, can we believe he would go to the trouble? I do.

In my opinion, Martin, Turnoi, John O Shei, Sludge and the ubiquitous Silverboy are all individuals.

Oh, why do you think that then?

Sludge seems to be sincere. SB is definitely SB, when de doesn't uses a different handle. However, Martin, Turnoi and O'Shei are all the same person. Now you probably think that Turnoi's level of English is not good enough to be the other two(numerous others also) and that's why I compliment him on the hard work put it copying and pasting.
