New to this… Is it possible to create a bot that posts constantly on different subreddits?

I just got into reddit a few months ago since my ex, who is a long time user, showed me how it works… I’ve gotten really into it since then, especially certain subreddits he knows I love going on.

Well recently I noticed on those subreddits an abundance of newly created accounts posting stories of relationships situations that seem extremely familiar to many of ours. Some of these post even have my name included so that made my assumption of my ex “trolling” me stronger.

There’s so many of these on all the subreddits I love so it’s hard for me to understand how this is possible unless the person is using bots. It’s really starting to affect me that I can’t even seem to figure how a person can do this.

Is this possible, for bots to create new accounts that consistently post the same stories but with different story lines and characters?
