Their structure was always the same (except MishaYo, who is only doing with his account fixed matches)
Adkensbet, why are you lying?
By any chance, can it be possible that polasaz = MishaYo? They both had the same mistake when they wrote
adkensbet instead of adkinsbet as you can see
here MishaYo have written. It barely can be a coincedence that both the user had the same spelling error for your website.
I think I have read that Adkinsbet already believed that this user is behind this. I don't think people make a typ error of writing adkensbet instead of adkinsbet, out of 200 people maybe 2 do.
They also have the exact same way of writing, always using the same writing style and emoticons. The content of messages is also the same.
The chance that MishaYo manages this account seems to me something like .. 98%
