How to avoid posting time on Reddit?

With the few works of yesterday, a few karmas has been upvoted, and can see there is increasing in number. But a few hours later it was still in the same old karma credit. Even though I have checked the people who actually downvoted or not where those upvotes still remain the same.

The question is where these newly coming karmas getting vanished often in a while. It's day 2. Any idea of what's going on?

from my experience it's mainly connected to two things:

Reddit account
Proxy

use good, high quality proxies and a good account and you should be able to post quite a lot
