I was told that my top tell was that when I was civ, my posts read like they were written by a first grader in the worlds worst school district since my typing is SO horrendous, and I just type & post without rereading what I wrote. When I am bad, on the other hand, they looked like they were written by a fairly educated, rational adult. Because I proof read them & corrected the errors & basically "polished" the post while going over them to make sure I had not made any baddie slips.
All you had to do is look for the word "because", and if it was spelled right, I was bad. I pretty much ALWAYS typo it as "becasue", so now I try to not correct spelling errors in my game posts.
Bonus side effect? People have stopped pointing out my errors pretty much altogether
