By default the comment will show up only if you request upvote for other steem user. Check the box to hide it.
How Does It Work
You can request an upvote from @tipU for your own post or a post made by any other steem user. This is onsidered as a promotional service that will increase the post's visibility by ranking it higher on hot/trending sections. This is especially useful if you're creating great content and want to build up your followbase.
Auto Refunding
If by whatever reason @tipU can not upvote the post (including the blacklisted author), @tipU will automatically resend the payment. Also any amount that could not be spend on upvote (@tipU maximum vote value is the limit here) will be automatically resend to the user.
If there's any unexpected error and you haven't received the upvote or the refund, please go to investors section where you can monitor and withdraw your deposit (any payment for upvote request is considered as a deposit before being automatically used to fund the upvote). You can also check #support at @tipU discord channel.
