I got a bunch of upvotes from 3Speak back in the day, it's good. Just be careful you don't say anything remotely critical (even trying to help them improve), and NEVER say anything negative about Zionism. If you stick to those rules, you'll continue to get upvotes, but only for the first few videos and then it trails off once they know you're hooked up with their platform.
Better free platforms are now available, including LBRY. I'm currently the only cannabis content-creator there! It doesn't require Steem, so people all over the world can watch, comment, send crypto tips, etc. And there's no monthly fee, which is always nice too. :)
