The Official ACM demonstrates "free" and "Open Access": TheWebConf links to peer-reviewed articles from: https://www2018.thewebconf.org/proceedings/ where the target URLs are at acm.org. When a human user navigates to one of the article URLs from that webpage eg: https://dl.acm.org/authorize?N655043 it redirects to: https://dl.acm.org/authorize.cfm?key=N655043 and they wait 10 seconds to be redirected to: http://delivery.acm.org/10.1145/3190000/3186960/p127-taelman.html?ip=84.72.1.173&id=3186960&acc=OPENTOC&key=4D4702B0C3E38B35%2E4D4702B0C3E38B35%2E4D4702B0C3E38B35%2E4DD68F0663C025AA&__acm__=1525163409_90e4d5315b181d6e86be36180f6e54e9 Note my IP in URL. That URL has lifetime of abut 10 minutes. Returns HTTP 403 afterwards. Alternatively, fetching: https://dl.acm.org/authorize?N655043 redirects to: https://dl.acm.org/citation.cfm?id=3186960 Note that neither the HTML or the PDF representations are publicly accessible (at the time of this writing). There is an access barrier ie. one must either purchase the article or sign-in, or if connected through a network (subscribing library/institution), then it can probably be accessed. Requesting the DOI URI: https://doi.org/10.1145/3184558.3186960 redirects to: https://dl.acm.org/citation.cfm?doid=3184558.3186960 Same as above ie. no free/open representation publicly available. The PDF/HTML representations used to hyperlink and point at something like: https://dl.acm.org/ft_gateway.cfm?id=3186960&ftid=1958645&dwn=1&CFID=28025596&CFTOKEN=214620b772eeb99d-7920D5E5-F234-2DAE-E26934C2F2C44CAA which redirected to the delivery.acm.org URL as mentioned earlier. Fetching without `User-Agent` header: $ curl -iLk https://dl.acm.org/citation.cfm?doid=3184558.3186960 returns: HTTP/2 403 " 403 Error - Access Forbidden We are sorry ... ... but we have temporarily restricted your access to the Digital Library. Your activity appears to be coming from some type of automated process. To ensure the availability of the Digital Library we can not allow these types of requests to continue. The restriction will be removed automatically once this activity stops. " Super!
