You remember those Reddit Skype groups where people used to upvote each other's posts...do you think this could work? Asking because I have a community of 100+ people that can upvote for the benefit of the community...
I'll share some more methods to get free upvotes. These can also be used to channel upvotes towards a specific post or comment, essentially increasing exposure:
Soar.sh currently gives you 2 upvotes for free; just input a link to your post or comment
The subreddit /r/FreeKarma4U allows posts which just asks for karma, or you can simply comment in an existing post there
There's currently an active thread here on Black Hat World which gives 5 free upvotes: /seo/free-5-reddit-upvotes.1112071
Apparently, there's a free upvote exchange called Social Clickers. I haven't used this one, but could be worth a try
I'm /u/Licheus on reddit. Feel free to send me a Personal Message with your link and I'll give you an upvote =)
Here's a trick to get a long-lived link in on reddit using just a few upvotes:
Find a small or "spammy" subreddit. Filter posts for all time and see if a few upvotes could send your post to the top. Obviously, you'd have to post something relevant to the community to avoid getting downvoted or have your post removed (although, many of these subreddits are poorly moderated anyway).
Example subreddits to try this in:
/r/clicksforbeermoney (1,610 subscribers. 9 upvotes would place your post as the 3rd highest of all time)
/r/beercoins (744 subscribers. 8 upvotes would tie your post for the number 1st spot of all time)
