OP, sorry but how did you find that person's post and distribute your 11 sMerit today?
the post was made early last month. and its position is in the middle of the thread.
just my assumption, you are trying to help the account to rank up faster by giving Merit.

but if it is indeed your fault for trying to send Merit, you can create a thread on Reputation to explain your mistake. never be afraid if you are doing something right.
