I agree with you because there's a big chance that you are right sir. It is very hard to believe (IMO) that a high-ranked member which also means being old here in the forum doesn't aware that merit begging is strictly prohibited knowing also the fact that the issue regarding this was already been discussed here in Meta so many times before so there is no excuses for him.
That account should be reported and let the mods hear his alibi (I bet it won't be valid

). But if ever this is not a bought account then he still did a mistake and liable of what he did.
People make mistakes it's within our nature. Far too many people around here are to quick to judge, and react by tagging them. I respect Jet Cash for actually looking at the user account, and determining that it might not be worth ruining his reputation over.
Even high ranked members can make mistakes, and not be aware. If he doesn't learn from his mistakes then he'll likely be found out eventually, and can then be tagged. But, a one off in this scenario isn't that bad in my opinion.
Informing them via personal message that asking for merit is frowned upon would be the better option.
