Actually to make your claims correct the following would need to be true.
1. UO is magically more cheat free than other games of similar types/playstyle.
2. UO is magically more cheat free than other similar games, despite being so much easier to cheat in, much much easier.
3. UO is magically more cheat free than other similar games, despite there being next to no enforcement against cheating.
4. UO is magically more cheat free, despite being a lot more annoying, frustrating and hardcore than other similar type games. (library turn-ins, looting, resource gathering, healing, etc. etc.)
5. The numbers on those sites are wrong.
6. The staffers and players who have said they cheated in some fashion are somehow magically not an approximation of what the rest of the game are, they're simply a magical tiny minority that happened to gravitate there.
7. Those you know are somehow different than other MMO players and of course tell you if they cheat, despite knowing that you'd probably throw them out or report them.
And so on and so forth.
Wow - 4 Straw man fallacies and 2 unconfirmable bits of hearsay which are most likely made up from nothing. Bravo, you can BS with the best of them in DC...
And, #5 can't be use to prove anything for the following reasons...
1. Counters such as those can be set to any starting number by the owner, and can in many cases can be set self-increment to make it look like more people are downloading than is the case (the counters keep track of the real numbers internally, and can be checked by the page owner easily). Anyone that's ever used a free counter on their web page for anything can tell you that.
2. Said cheats are universally known to fail with client patches and/or server publishes, and require reinstalls from a new version that have fixes applied to overcome the patch/publish changes. so, if one assumes a new download for every other patch & publish (there have been 47-48 full publishes, several times that in incremental mini-publishes, and several hundred patches just since the release of AoS in 2003) it's fairly safe to assume that each 100,000 downloads listed probably reflects about 2000 users making at least 50 corrective re-downloads after game alterations, over a 2-3 year period. You can't even assume that each download with a different e-mail is unique, because most long-term players have probably used 3-10 e-mail addresses over the length of their playing, and probably different addresses from the ones their accounts are associated with.
3. There's no way to know how many of the listed downloads (initial, and re-downloads to correct for a patch) are from people who haven't played in years.
Give it up... You're beginning to sound like USAF General Jack T. Ripper from "Dr. Strangelove"....
