MemeCannon
Currently a .NET Core Console app using the Twitter API like Tweetdeck. A twitter user would authorize the MemeCannon app via Twitter, that gets a list of images in a local folder and posts randomly to their Twitter with a random/fixed set of hashtags. Everything is well below their spamlimits, 1-2 tweets per minute. No install, just run. I've been using it with MemeFarmers mega meme archives for a couple months. Turn it on and it just runs thru 500+ files until you stop it or it's done. It's running right now.
X:\MemeCannon\Bernie
X:\MemeCannon\Biden\hashtags
Builds out a dynamic menu and you choose your campaign/folder and default hashtags.
