Again, you can give gold to pretty much whomever you wish. There isn’t anything inherently against policy in doing so. Our interest would be in if this person is a legitimate player, just giving or accepting gold or if there more to it.
We’re not going to be able to get into all of the particulars of the what if and various other examples of everything.
Is a written profile considered outside of game? Possibly. Do you think it links to illicit services, botting and exploitation?
I have always played on RP realms and I honestly have no idea what that is, but it sounds like giving gold as part of an RP event. Which I don’t see an issue with. Assuming your RP event doesn’t include giving or receiving thousands of gold to/from some random level 10 character on a brand new wow license. 
I’ll note the other account but an update to the article just went in and should populate in the next 5-10 minutes which should clarify some things.
