Does Reddit know if certain accounts continually upvote the same person?

I'm currently working on creating some reddit accounts to later be used for upvoting my own comments. I will up and down vote other people with these accounts so they will seem much more legit. What I want to know is whether reddit will catch on that these accounts will all give upvotes to the same user... Even if they also give upvotes to many other users?

Hope this makes sense :-/

If you leave a footprint then they will be able to track you.

ie. using the same IP's, cookies, etc.

Yea they will so make sure to use proxies and multiple accounts. It's not worth having all your time and effort be for nothing if reddit detects your footprint.

Ye I have anonymox premium, and for each of my account I will use a specific proxy. Do you think Reddit keeps a record of IP's associated with each account?

I don't think Reddit really keeps a record of IP's used for each accounts since people go on vacation, use their accounts from different computers, etc... So long as your accounts don't cross with IP's you should be good.
