It appears to me that POB is the victim of tag spam.
I've noticed that many accounts include every lucrative tag on every post.
It's becoming a joke. Every post seems to list LEO, POB, CreativeCoin, Archon, STEM, CENT, etc. Regardless of the content of the post.
The people who spam the tags also appear to be the first to dump the coins.
After dumping their alt-coins, the spammer dumps the HIVE. So, Tag-spammers are hurting they are hurting the whole system.
I sold a fifth of my POB when the price was over a HIVE. I did so because I realized the spam would destroy the value of the token. Of course, all of the tokens are being negatively affected by this affliction; so it is hard to find a safe haven on the platform.
