Like i said, for making changes I get it. I just want to read a debian specific wiki. They block archive.is too. You can .htaccess block specific pages for form submit action.
I tolerate excessive captcha for every other site as well.
I guess whatever spam control system they use is simply blocking all VPNs rather than more fine grained check if the request is for read/write
Captchas are a more acceptable solution if they can't make it more granular. Perhaps they object to captchas because foss vs proprietary third party?
Capchas are bad. It will trow users away.
They are not any worse than a 403 page?
A .htaccess block doesn’t help if you’re trying to mitigate ddos attacks. Your server still has to expend quite a lot of resources to do htaccess checking vs an ip firewall block is just one hashtable lookup at kernel level.
They are giving a 403 which looks a lot like .htaccess. You can't do a whole lot of DDosing from a VPN IP either due to data cap and connection count limits per account.
