Hive is not the solution to this problem. There were several cases in the past of dapps built on this blockchain that had the posting authorities of the users and got hacked, basically giving full permissions to write anything. Not different from Twitter. I am sure, if there was enough hack value, a simple social engineering attack would crash most of the dapps here and would create serious damage.
Also please, this tactic of asking to interact in exchange for upvotes has been proved ineffective several times. Worst, most often has been seen as a spammy behaviour from outsiders. If you want to build real interactions outside of the chain, stop cutting corners. My two cents.
