I’d never promote it on an unrelated site or forum that had nothing to do with that, or somewhere where people definitely wouldn’t be interested. And although I definitely wouldn’t just straight up promote it in a discussion thread, if what we were discussing was related to my story or my characters, I’d probably use it as an example, but only share my story link if someone asked for it.
Everywhere? I’m not really a promoter, though I know I should be.
I haven’t really promoted my story yet, but I definitely will not promote on unrelated platforms and unwanted audience
