I recently had my post boosted by @hottopic and @hugewhale who promised 20+ upvotes and 50+ upvotes respectively. My post now has 55 upvotes and I do not know who came short on their promise number of upvotes. I also do not know if these really happen but these are not free.
Below are the messages they sent me through SBD/STEEM transfer memo.
Have you experienced using these boosters? Any comments?
