[3] Did this affect anyone (e.g. they were using their hacks in PvP)?
Affected the player Mr.Memer Man, who were going to trade his paladin’s shield for a influx he supposedly had.
[4] Evidence. (If this includes chat, Phase link one or more messages)
I have indeed found evidence of them suggesting they scammed another player a separate time. I do not believe that Oofity can be trusted to follow the rules of DG.
Evidence:
Seems that Rafaelgamerplay gave Oofity a wooden boomerang expecting 60g in return. Oofity replies “get scammed”.
Rafaelgamerplay then questions Oofity about this exchange, and seems to get ignored.
While I cannot prove that Rafaelgamerplay got scammed on the day above with chat logs alone, it does reveal pretty well what Oofity is like, and I do not think that another accusation of scamming put in today is merely a coincidence.
