As per the
Dedimania thread, I looked at all the cheating logins mentioned in this thread. If present, I deleted their cheated entries and, in some cases, their remaining valid records too.
Additional cheaters found by looking at a few hundreds tracks: tr3nix, cogger, ganster1994, szebetomi, streetzn, admin_nadeo2, berry111, badrobot, s8t, blackmamba08, hahner, mucho__lol, nrg7, ugfiufitz, dmstr, citrix_retired, seregahop, triz, u15katze, naaldje93, smiths, ichwaresnicht, samiboy90, klauscittyrunner, jacob.., online_acc., nico.9753, pitt1, lukasbeer, peablo, beef78, volldeppzocker, mr.krtnsn, tr__333tirfally_66, ________player_______, and schwarzlicht1337.
Some of these haven't been active since last year though.
Many hundreds of cheated or otherwise bogus records perished in the process.

If anyone knows of additional logins or tracks to check for cheated/erroneous records, please PM or mail me.
Edit: one more cheater purged: mixalakis_7.
Edit2: and three more: flatlus, ddfft, loff_oil.
