There are these accounts that just post a link to some kind of product. They start posting as soon as they create their account, and they never make any comments, just post a link. I also noticed that these accounts always post between 5am to 9am EST. Its usually a different account each day, while some accounts will continously spam a certain sub. I've also noticed one account u/rajoshi111 that seems to be using upvote bots on its own posts.
Some accounts which I suspect are bots go by really generic usernames like u/peter123, u/webonline, u/rajoshi111
