Check out James Corbett of the Corbett Report - @corbettreport - he has not been 'deplatformed' (yet) but his videos are being hidden by YouTube algorithms. Some of these videos even reached 5 million views but you can't find them even using the 'exact title' in the search.
@theouterlight has been deplatformed but is regularly posting to Steem/Steemit and DTube. Same goes for @titusfrost.
All of these content creators often recommend/mention Steem/Steemit/DTube in their videos and I think deserve more attention and consideration.
Thanks, great idea!
