Do Reddit upvotes from smm get you banned?

It all depends on the panel that you're using.

If you're using a completely bot-driven panel that uses new accounts or accounts with karma problems, you're probably not going to get the result that you're looking for.

I can't speak from personal experience but if you think about, let's suppose Reddit were to ban everyone just because that person received 100+ bot votes. Wouldn't we see more people try to buy 1000 upvotes just to get a Redditor banned as a target? Reddit can't tell if YOU or another person bought upvotes for the target user/post. They can tell it was botted but I doubt they would be able to know if you bought them yourself or someone bought it just to get you banned.
