Someone will look into these accusations and do some detective work as far as the blockchain is concerned I am sure, but I do want to point out that you should have some balls and use your main account when accusing people of wrongdoings. Don't be a coward, it's not like you will get into trouble for posting things like this. You might actually gain some recognition in the community for catching cheaters.

I get it, you're scared of these users for whatever reason. I just can't see why unless they're cops in your local community and you're scared for your life.
