Reddit questions about limits

Today I'm going to write python scripts to post to reddit, and to get upvotes with multiple accounts. I haven't grew any reddit accounts so... Answering this questions will help me:

How many accounts can we use per IP without a high risk of ban ? Reddit limits it ?
There's a limit of how many upvotes a user can do every N minutes ? Like when we make posts...

Thank you

No idea about the limit per IP and upvotes per minute, but i would make the script upvote some random things, cause if your accounts only upvote things from the same domain/user, it will be flagged quick.

1 IP 1 Acc I used 2 acc with single IP, now IP is banned and acc shadow ban

1 IP per account, anything more and then you risk all of your accounts in one IP being banned if you get in their radar. Stay safe, delete your traces, use one IP per account, and don't only upvote your own stuff, you will be more than fine.
