Well today's issue with Blogger, at least for me is replying to comments.

Publish comment from others. 

Enter a reply. Click Publish. Wait, wait, wait, wait, wait. Watch the reload circle spin and spin. 

Error message: Please verify you're not a robot. Repeat process. Wait, wait, wait, wait, wait. Watch the reload circle spin and spin.

4,5,6 tries later, Huzzah, my reply gets publish. 

Fucking Bloooooger. If it wasn't free they should pay users who use their platform. 

But how does it know I am a robot?
