It does indeed sound very much like pointless spam.
OP, if you are trying to market something, spamming will just annoy people. Concentrate on quality instead of quantity. That's a much better (and more likely) route to success. If you are not trying to sell something, and are instead talking about crypto social media bounties, then again quality ahead of quantity is better. If you are marketing something for someone else, they won't want to be associated with low-quality spam.
