Happens on my Plus account, have been seeing other reports on Twitter. Every 3-5 messages I have to solve 5 puzzles which require on average 20 clicks per challenge (each puzzle takes avg 3 clicks + 1 submit button) before I can continue my question (between browsing pictures and submitting the answer), and if I rush through and get one wrong, it'll tell me at the end and make me do all 5 all over again. Repeat every few messages.
Massively flow-breaking.
1. Plus accounts pay $20+/mo (you can't have bots use it for free)
2. No point proving you're human, you already provided a CC.
I haven't seen this. Needless to say, if I do see it, I'd just stop being a customer and deal with Bing & other services.
But you didn't even provide a screenshot :P ?
