Many projects turn away from bounties, because it's being abused and misused.
More than 50% of bounty hunters who use social media as their tool, have accounts created just for that. Meaning they're mostly spam accounts which no one cares about, no one retweets, no one views. And as such is worthless.
I've done an experiment, where a bounty hunter had more than 15k followers on twitter. And when i checked his stats, it was like maybe 20 views of the post and not a single click or retweet.
Not surprise. Cause when i started work here as a bounty hunter i did same thing like that. I stopped when i understand actual meaning of spam (when my account was banded for spamming). Now i just try to work with reliable project which have good future in crypto industry and try my best to advertising their product. It's not 50% i guess around 80% of bounty hunters who use social media as their tool. In that case i think other campaigns are much reliable than social media campaign (Signature, YouTube, Referral, Article etc).
