I am not a robot!

Why is captcha verification coming up more often now? When I go to edit a question more than once, I get The Page.
This even happens on sites where I am >1k rep. I hardly think it's necessary; I don't think anyone over 1k rep would spam, especially on editing his own question that he just posted.
It's just not a reasonable path for a spammer.
A spammer would probably just post a spam question. Not edit his spam post 2 times in a 3 minute window.
