@myothuzar we do indeed see the transaction.
It seems our bot did not catch it it could be to
the instability of the RPC nodes lately.
You are always suppose to receive a wallet memo
back upon buying an upvote. If you did not received
a memo back then something is wrong with your entry.
You can always contact us when such a situation occurs.
We will send you a refund for the 0.5 SBD.
The same have happened to me, with these 2 posts:
