So I got an Incident ID and some captcha mumbo jumbo for attempting to browse that site. Apparently they don't like visitors. Feeling generous today, I decided to not inconvenience them further.

Same. Not going through a captcha for a random link.

Ironically, if you throw up road blocks for human visitors, the only ones who take the abuse will be bots.

I too detest captchas. I found the paper elsewhere:

perhaps it's your IP/network. I'm not getting any of that

Looks like the effect was temporary, it's gone now.

If you're not aware 3M (and other companies) now sell electrically de-bondable tape. It's used in consumer device manufacture where it would otherwise be expensive (or dangerous) to remove an item for replacement like a lithium battery.

Now a worn or damaged battery can be safely bonded down as it normally would with a PSA (pressure sensitive adhesive), but then after applying some 30V for a couple of minutes ions in the adhesive cause it to become easily and safely removable/repositionable.

Until last spring my bots never saw those Cloudflare CAPTCHAs despite not taking any serious evasion measures. Then all of a sudden they started getting them 100% of the time on sites I was crawling. For that particular project my webcrawler was cued by a bookmarklet, like I was picking the pages to import manually so switching to getting the data right out of the web browser got my system back on the road.

I always had the feeling that the Cloudflare CAPTCHAs discriminate in various ways, for instance I would see them much more when I was browsing on a Samsung Galaxy tablet than when I was browsing on an iPad. They disproportionately affect the disabled and I wouldn't be surprised other vulnerable populations.

If I had anything to do with it having a CAPTCHA or a GDPR popup would be an immediate WCAG fail at A level.

Is this how the iphone battery replacements work by passing a 9v battery through it?
