Feature request, block comments depending on user-agent

Hi @jaegerschnitzel,

at the moment we do not check the user agent and the filter for adding own patterns is not supporting the user agent too.

The problem is, that the user agent is very unreliable and Chrome is starting to deprecating it already:

https://www.zdnet.com/article/vivaldi-to-change-user-agent-string-to-chrome-due-to-unfair-blocking/

The whole history of this feature is a disaster.

I do not think this will ever be part of ASB because of the unreliability and easy modification of this string, but maybe we can add this to the regex pattern feature, so that you can build your own solution.

I opened up an issue on Github for this:

All the best,
Torsten

I tried the patch and it doesn’t work, because the data is not available at the state we are processing the comment. This needs more work and I am not sure if this is necessary for this unreliable check …

Maybe you can block this at the server level much easier (this code would be for Apache/.htaccess):

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} python-requests/2.23.0 [NC]
RewriteRule .* - [F,L]

Then the whole request gets denied.

Can you try this and report back @jaegerschnitzel?

Thanks and all the best
Torsten
