> only viewable by the CO it still shows their name as FTF
not an issue if, per my suggestion and the way it's handled for every other cache type, not the first log but the FTF log is taken
> Also a virtual log can be deleted by CO etc and this takes away that FTF stat from the records
they can just log the cache again (if all conditions are met), include {FTF} or add it to their ftf list, and it'll be counted by PGC. If the conditions are met the owner is not allowed to delete the log and there's nothing you can do to prevent them to add them to a list.
If you want something that's cheat-proof you'll have to find another game then Geocaching.
