How many times is SO going to ask if I am human?

I appreciate why we have human verification and think it is a good thing, but I am confused as to why I get it so often. 3 times today already, twice yesterday.

Annoyingly, it always seems to happen when I am answering a question from the train, have limited signal, and am fighting to be the first answer in. I don't even know if this could be the reason why somehow.

The question is - am I using Stack Overflow in such a way that it is specifically targeting me as a bot? If so, what behaviour do I need to avoid to stop being targeted so often? It is very annoying and often causes my answers to be delayed by 5-10 mins, until I get to another good signal patch.

Anecdotally I remember hitting the CAPTCHA more often than usual during the summer when I was somewhere in the middle of the Aegean (boat programming IRL) and network signal was shaky. –  Yannis Oct 19 '12 at 17:31
    
Also strangely it only happens on my iPad. Never iPhone or laptop. Also often soon after or just before "sorry something bad happened" –  Pete Carter Oct 19 '12 at 17:36

@YannisRizos What would you recommend for someone who wishes to start programming on a boat? –  mikeTheLiar Oct 19 '12 at 18:06

I think it's happening because instead of typing a character at a time like a human, your data is being sent in bursts as you pass into areas of reception. SO sees this as you typing faster than a human could. When I paste a lot of text in from my editor, I find it gives me a captcha unless I also do a little manual editing before submitting. Your poor reception (or buffering in the transmission to your network) is preventing single characters coming through at a time.

Switching IP addresses (quite common with mobile connections) also triggers the checks. –  Martijn Pieters Oct 19 '12 at 19:55
