That are a lot of user pings. This kind of stuff quickly gets you into trouble on HIVE, as people often don't like mass pings. Besides, you say those people have excellent Splintertalk content - which is not true. It is a list of large Splinterlands stake holders, with several that have never created a single post.
You don't need that to get attention. Doing videos is a great way to catch eyes and upvotes.
