Ask HN: Captcha Alternatives? 47 by ev1 | 42 comments on Hacker News. TLDR: I help with a gaming community-related site that is being targetted by a script kiddie, they are registering hundreds of thousands of accounts on our forums to 'protest' a cheating (aimbot) ban. They then post large ASCII art spam, giant shock images (the first one started after we blocked new accounts from posting [img]), the usual. Currently we use a simple question/answer addon at registration time - it works against all untargeted bots and is just a little "what is 4 plus six" or "what is the abbreviation for this website" type of question. It's worked fine for years and we don't really get general untargeted spam. I am somewhat ethically disinclined to use reCAPTCHA, and there are some older members that can't reasonably solve hcaptcha easily.

Tell HN: Check medium's localstorage if you use adblock 54 by ev1 | 4 comments on Hacker News. If you have uBlock or similar, it appears medium logs all analytics pings into HTML5 LocalStorage and will keep retrying to send them (and apparently periodically change domains and subdomains to try and send them). I had tens of thousands of entries in localStorage, wasting quite a bit of space, all of them at least 400-600 characters or more. Each time I scrolled it'd add a few dozen more in, to the point where devtools was freezing. Ridiculous. Example: https://ift.tt/2QAyqu0
