This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Created attachment 1614 [details] Screenshot of error message (403 Forbidden) I use pear extension for send request to w3 validator check: https://pear.php.net/package/Services_W3C_HTMLValidator https://pear.php.net/bugs/search.php?cmd=display&package_name[]=Services_W3C_HTMLValidator&status=OpenFeedback&bug_type=Bugs I create question on stackoverflow: http://stackoverflow.com/questions/31097106/validator-w3-forbidden-403-error Example request to check cgi script: validator.w3.org/check?uri=http%3A%2F%2Fwww.yandex.ru%2F&verbose=0&ss=0&outline=0&output=soap12 Full error message from validator.w3.org server: Forbidden due to abuse Access to this resource is denied due to abuse from your IP address.

I can duplicate this problem no matter what IP address I use.
Check your link in browser url pane Exists problem with copy link from bug tracker to my browser url pane I see wrong url, after inserted link from clipboard: "http://validator.w3.org/check?uri=http%3A%2F%2Fwww.yandex.ru%2F&verbose=0&ss=0&outline=0&output=soap12%20%3E%3E%20validatovalidator.w3.org/check?uri=http://www.yandex.ru/&verbose=0&ss=0&outline=0&output=soap12" that url it wrong and that query redirect to normal w3c validator page, but it url-address our not interest Need correct url: "https://validator.w3.org/check?uri=http%3A%2F%2Fwww.yandex.ru%2F&verbose=0&ss=0&outline=0&output=soap12" After send query - w3c blocks any ip-address on five or more minutes...
The output=soap12 option is obsolete and should not maintained and should no longer be used or relied on. We recommend instead using the current HTML checker with the out=json option.
