Hey, this is a good post however one of the rules of my community is that users do not self-cross post their own work. @andrastia addressed it already, as a moderator of my community so I won't go over it again.
I will say that self-cross-posting must be done with relative care as blasting a post across multiple communities may not be seen as a positive thing by the owner of the communities. You're better off selecting one to post into and dropping the post directly there. It's your choice of course, however I've rarely seen accounts that incessantly self-cross-post go that well.
I hope you'll choose THE WEEKEND community to post into in the future and you may like to read the POSTING GUIDE pinned to the top of the post-feed and the rules which @andrastia has also added in a comment on this post.
All the best.
