What I meant was... The comment could have come either as a warning or an exposition... Then "repeat" posts (or maybe I should have said repeat offences, post-warning) gets down-voted. Because at this point it wouldn't be a matter of "doesn't know any better" anymore.

And "generally an accepted idea?" That's a justification?

I think it is also generally an accepted idea that only posts related to communities be shared in those communities. And unrelated posts are usually ignored or muted, with a comment explaining why. But down-voting? That's kinda draconian don't you think?

Which remains my point, you could have pointed it out, and I'd have simply taken off the tag. Any reasonable person would have taken it off..

still my two cents. But of course, feel free to do you.

Cheers
