Hi guys, here's also my opinion about the site ... while it's a nice simple design which I appreciate, I'm facing the same issue about the Accuracy ... 38.92% after 1k+ resolved it's for me hard, very hard to believe
I have this same issue with this website, so I find it extremely hard to use.
I hate that the captchas are all case sensitive but have many letters such as V, O, P, Z, X, & C which make it extremely difficult to know when they are capitalized or not. Overall I find that my accuracy is extremely low and it takes me on average 3-4 tries to just get 1 solved.
I don't recommend this site to anyone as it ends up just becoming extremely frustrating.
