I don't care if account age is the number 1 factor in anything, I am saying that I have used hundreds of fresh accounts, all created on the same day, on reddit, over years of testing, and never had issues getting pure spam on dead subreddits with zero traffic upvoted with those accounts. There just is NO reason for reddit to ignore the upvotes from 10 accounts if they count them from 2 accounts. From reddits point of view, the accounts are all different accounts. Unless there is a leak somewhere else, reddit shouldn't care. I have seen many posts over the years get brigaded and mass upvoted or downvoted by brand new accounts, thousands of them at once.
With 100% certainty I can say that I can get 25 upvotes to stick from brand new accounts all created on the same day, not aged at all, on dead pure spam posts. The accounts wont be banned. The post wont be deleted. Nothing bad will happen. The upvotes will be permanent. The accounts will work perfectly for everything. I am not some magic guru with a hidden trick. I am just stating the facts of reddit. If there is no leak, the upvotes should stick whether 1 day or 100 days old.
I didn't tell anyone they don't need that many accounts. I was referring to my own use.
