It is annoying to some extent but my thoughts are that we're here to get people interested in stats. I got the impression from this poster that he's a high school student so maybe this would be a good time to talk to them about sampling and give them direction. Also at that age they may think this is a stats project let me search for stats websites and post my survey there. I think we can take negatives like this and turn them into a positive. That being said if this becomes overwhelming I'd then have a change of opinion.
I was annoyed but still took the survey because I'm an cynical optimist and thought who knows maybe this kid will be the next Denny Borsboom.
