I’ve moved this out of #feedback because that’s for forum changes only. You’d have to contact MrEyeball directly for any changes to features of the main RealmEye site.
But for discussion purposes:
Deca did add a <Creation Date>
for new characters (patch X.21.0), although as Doc’s post linked above implies, RealmEye would require this info to be publicly visible to other players, and therefore MrEyeball’s bots, for it to be usable. I don’t know if it is visible or private info.
Although even if it was visible, it’s only a day, not a date/time, so say if you created several knights on one date, in several empty slots, they’d all have the same date. So on its own, I don’t think this would get us any further than where we are now, with RealmEye unable to tell the difference.
