If you're a Vine fan, chances are you have, or will encounter unwanted comments on the videos you post to the service. This can be especially worrisome if your vines are set to public, as anyone can read NSFW language in comments.
Of course, you can delete comments posted through Vine's iPhone app at any time. But if someone is repeatedly showing abusive behavior toward your followers and spamming you in comments, you should block them.
Though this won't block the user from commenting on your posts when they're viewed through searches or hash tags, it will prevent them from following or messaging you on Vine. In this post, you are going to learn how to block a user on Vine, report abusive behavior and flag sensitive media.
