Why do you send transactions with your posts to @minnowsupport? It is upvote bot but definitely not a bid-bot. They are giving upvotes for FREE. You just have to go to: https://discordapp.com/invite/GUuCXgY, register, go to the Upvote channel and there you must write "$upvote urlofyourarticle". (about 10 cent worth upvote)
If it was just a mistake, you should write them and your transactions might be refunded.
