What is happening with these (no idea what they are called)? They showing up all over the place. Have not seen them in threads until today.

 

They are captcha requests in place of YouTube videos. Google/YouTube must not like something they are seeing from your requests.

YouTube videos are simply embedded on CorvetteForum. They are not hosted by CorvetterForum. This means the connection is between you (the viewer) and YouTube.

 

Must have been an intermittent thing. They are all gone now.
