The best thing that can be done is that, a PGP key should be made mandatory for signing up on this forum. This does a lot of good.

1. It prevents account farming because I believe making a huge amount of PGP keys is definitely tough.
2. It increases security. As a person who is genuine usually holds only one key and hosts it on a public server.
3. On creating an account, the person should be staking his PGP Public Key on a thread and he would have to use only that PGP keys while he trades via that account.
4. Also, in a case an account gets hacked, a simple message from the account linked PGP key should be signed to verify the authenticity of the claim.


This would definitely make this forum a better place, but this is according to my knowledge. Maybe more knowledgeable people here might have something more substantial to say.
