As stated this is an EvenBalance violation that is enforced by PBBans. Only EB know exactly which violation # correlates to which hack and this information is not disclosed. If your member believes the violation was triggered in error he will need to appeal the ban by clicking the "Appeal This Ban" tab on the actual ban link and following the simple instructions provided.
As this was a direct detection of a cheat violation made by evenbalance themselves, the appeal will also include a troubleticket link.
The ticket should include all processes that were running at the same time as the cheat violation was raised.
This will help evenbalance staff determine if a mistake has been made or not, as the case maybe, although with 1,458 bans issued for #70819, and rising, I think its safe to assume that your member was indeed detected by PB software with cheat related files on his pc.
