How many of the "introduction" posts are genuine?

Hey Steemians..

Really curious what you think is the ratio of genuine vs scammy intro posts?

I get the feeling it has shot up in recent days. Is that trend is set to continue, as more hoards of people arrive? Why are people Upvoting posts that are very conspicuously spammy? Perhaps a lot of people are trying to game the Upvoting reward system, and they know that some posts on that tag get huge.

Thanks for any thoughts on this..
