Unfortunately some traders go undetected until a deal goes bad which then draws our attention to their activities, as you folks are also noting.
We are constantly removing the sales access of folks who's only interest is in lining their own pockets from the sales section.
If anyone would like to point out anyone who you suspect to be a dealer, please feel free to PM a member of admin so that we can look into the matter --- the more eyes on the job the better.
All the best Mick
