Would be cool, but I don't think I've ever seen more than 3 downvotes on a post...
I keep thinking it one had to have X karma in order to post... but don't necessarily want to discourage first time posts. The spammy accounts tend to be all over the map... some see about 3/4 quality post and 1/4 crap, others the inverse, others still single post, decent quality and others single post, crap.
Not to be negative, just feels like short of immense development, hand curation is still, largely the best option.
Yeah, a karma entry level would be kind of neat... and I think quite effective. Just something that blocks random spammers, like 10 points.
It's something I've proposed in the past and I thought it wouldn't be possible? Maybe I'm recalling wrong.
