@cryptoctopus,
Yeah every tag got spammers! Therefore, I think you have to allocated % of SP to flag those spam contents as well! Hope STEEMIT dev team will fix that problem soon!
For me this is a good sign! Last time we got huge amount of errors before STEEMIT dev team launch new version of STEEMIT :D So, I think this is a good sign for us! Probably they are testing something much more powerful like SMT!

Cheers~
