HiveWatchers was extremely aggressive after the break up. They wanted to avoid the situation where people dropped the same posts on both platforms.

SteemIt punished HIVE users in similar ways. It was a bad break up.

Having the same post appear on multiple sites is actually an SEO nightmare. Google down grades web sites that have similar posts. When sites have too much duplicate content, Google simply removes links to the site from its search engine.

NOTE: The cookie cutter sites on HIVE had a rel="canonical" reference on each page. When done correctly a canonical structure is supposed to improve the SEO.

I still use both platforms, but I avoid putting the same content on both sites. For example, I am playing inktober. I am putting an AI image on SteemIt and an hand drawn image on #hive.
