I got a few tonight. I dont think I post that often, but fell like Q's in the captcha have jappened when I post a lot more in the last year or so.i wpuld say about 40% of my capchas have a Q. My post generally don't get much attention,so I don't know if importance of post is a factor or not.
Just be aware that once seen, it can't be unseen. I worked for the district attorney and wish I could unseen a few things.
