Captcha Codes

Post Reply New Topic

So do I. I get so bogged down in the details of whether each letter is perfect or not that I often forget to see if the string of them make up a known word.

Its not you. My visual processing is good and beyond normal and i have problems with some of them.

Reason is that some CAPTCHA are crap and escew character and letters so you cannot tell them apart like 0 (zero), O, o and even Q. There are some text based CAPTCHAs that work and require the human do do a mathmatical or logical puzzle, those work well.

CAPTCHAs have been known to be brute forced, i.e. be included for users on facebook, the users is presented with the captcha and a reward, solves it and get to see a p0rn image or something, so there are ways around it, regardless how advanced they are.

Also in low cost countries, spamming operations have people who sit and break captchas, some of them are rather low entropy and only have a few words. Once that is done, they can just brute force in parallel: even if they get 99% error rate, at 150000 tries a second, that equals 1500 spam messages per second.

I have once before came across some that I typed in the right thing and it would come back wrong. The worst time to get them is on mobile browsers because with those no matter what you type in.

Now, I guess that part is helpful to me for when I do get a new smartphone! [/quote]

Posting here via a mobile BLOWS CHUNKS. Sorry Alex, had this been any other website, I would have been gone a long time ago.

I post using a Samsung S5 or a Samsung Note 4. It doesn't matter if I use the native browser, Dolphin, Firefox or some variation of Opera. I've used my sister's brand new I phone, and ran into the same thing.

You type your reply. You BETTER copy that reply because this is a 50/50 chance it will vaporize when you hit submit. Hit submit, and something about it can't handle compress...blah..blah.. must hit refresh. Hit refresh. Now you get a CAPTCHA, which is really the least of my worries. Hit submit.

Now the fun starts.

Did it get submitted, do I get bounced back where it doesn't look submitted, or do I get bounced back to the reply box with my typed message gone?

Now do I decide I want to bother to try and paste and do the happy dance all over again? Most of the time I do, but sometimes it's -screw it- and go on to the stuff.

I don't see how some turd manages to spam 85 topics on the general board in 6 minutes, and I fight for 6 minutes so post one reply. Obviously the CAPTCHA isn't slowing him down.

And I get some will say, "Who cares? I post via a desk top." But young adults have Mobil smart phones, and post almost exclusively from them when they are out running around. I do all my work via a mobile smart phone, and very rarely sit in front of a desk top.

Is this site that horrible on a tablet? I don't own one (no need for it).

So please do something about mobile posting. The young folks in my husband's support group says the mobile posting (view is okay) is a freaking nightmare.

It shouldn't be this hard.
