Hastag #promo-steem is very recognizable by some of the steeemians who joined at the start of the launch of steemit.com in 2016, at that time steemian who became the ambassador to promote steem with the theme #promo-steem is always supported by 
every time we hold a event or meet-up that discusses steem promotion.
But since the fall in the price of rewards obtained from writing on the steem blockchain that is STEEM and SBD, the spirit of steemian to do #promo-steem has begun to decline because they are disappointed with STEEM whose prices should go up because they are always promoting instead turning back to go down so that some instead they came to the conclusion to stop promoting steem.
In the future maybe I will review and write more about #promo-steem more often in order to promote steem to all steemians or even people who don't know what steem is so we need to explain what STEEM is and so on related to steem blockchain.
