The bots are usually associated with something negative, but not all bots on Twitter are tools to spread spam or to subvert the democratic principles of the West. In fact, there are some very useful ones. This is the case of @this_vid, which allows any user of the social network to download the videos and GIFs that they like the most.
“If you want to download a video on Twitter, it’s as easy as responding to a tweet with video by citing the @this_vid button.”
The bot has been developed by Shalvah Adebayo, a Nigerian programmer, and receives more than 7,500 requests to download videos and GIF per day. The operation is very simple. When you see a video or GIF that for some reason we want to save on our computer or phone, you just have to respond to the tweet in which it appears quoting @this_vid.
The bot will respond (although not always, due to the limit of 300 responses per hour) with a link from which the file can be downloaded. As you can see in the screenshot, if a request is made and the bot does not respond, you just have to enter the link.
The programmer designed the bot because where he lives, the Internet connection is not always stable, so he often preferred to download videos from Twitter to see them offline. Although this is a good reason to use it, any user can simply want a video to be able to resend it without having to pass the complete tweet or to use it in any project.
The bot works since May 2018 and you can not always download a video. Some accounts that upload copyrighted videos can block downloads, but in most cases it usually works. Twitter is not always permissive with this type of third-party services, so it is possible that @this_vid does not continue to operate permanently.
