My new pet peeve applies not just to social media sites (which tend not even to deploy this annoyance) but to any site that fancies itself either so special or so pursued by bots that they need to add a Recaptcha challenge to their login process.
Man I hate those things. I've been known to bail out of a login after being challenged to pick out images of "fire hydrants" after already picking out "store fronts" and "bicycles". Sometimes the images are grainy enough to challenge even the vision of a 7-year old, never mind these aging eyeballs.
I managed to persuade one publication to bypass that requirement on my account... on my serious threat of unsubscribing. The NYT is next. The next time they ask me to try again when I've already demo'd I am at least a smart bot and can distinguish most pictures of a bus from those of a fire hydrant or an empty stretch of freeway or someone's driveway, it's back to Reuters for me where I don't have to sign in. I happen to lack the skills to notice if the ads are any different when I'm not paying more directly to read the content.
Someone should tell these outfits that good bots are probably constructed by programmers smart enough to tell the bot to call a hacking module to bypass the Recaptcha process if the bot's first go at picking out "bicycles" versus "traffic lights" doesn't work out well enough to get logged in with purloined or illicitly borrowed credentials.
Oh, yes, by the bleeding nails of Christ, I hear you. Oh, yes, I hear you - couldn't agree more.
I loathe, loathe, loathe "Recaptcha" - absolutely loathe it.
And yes, for exactly the same reasons as you have so eloquently expressed: My ageing (bespectacled) eyes find normal stuff hard enough to handle, - but when asked to identify "cars", or yes, "garages", or "awnings" or "shop fronts".
The Financial Times and I had a discussion - a strong disagreement in fact, - when I brought this issue to their attention, as, unable to log into my subscription, - and constantly tripped up by this....sanguinary...l Recaptcha, I phoned them. They chose to blame my Apple computer, but did - the threat of cancelling a subscription, worked, as, given that I had paid for it, I thought it not unreasonable that I be in a position to read it.
They attempted to argue that they were doing me a massive favour by by-passing all of these things.
Now, strange to relate, The Financial Times phoned me today to ask (very nicely) how I found the publication and their customer service, and we had a lovely chat.
