IP Address Blacklisting / Captcha Impact

Hi guys,

Since moving back to Virgin Media I am seeing lots and lots of captchas appearing, many of them you have to go through multiple iterations, and some as many as 10!

I've used a couple of websites to see if the IP could be a "dodgy" one, and the entries that come back are:

dnsbl.spfbl.net
dnsbl.sorbs.net
dul.dnsbl.sorbs.net

I just wanted to ask/check if these are likely to be blocking the whole Virgin Media IP range, or whether other people have the same listings. I've been to the sorbs website and it seems to show an entry from 2005. I cannot work out if there is anything I can do to remove this entry as the site seems to be for more technical folk

Any help appreciated.

Those blacklists are used by email servers rather than web servers so won't have any impact on web browsing. You only need to worry about them if you run your own email server at home to send email out. I suspect very few people do that.

There is a browser extension you can install called Privacy Pass which should reduce the number of Captchas you see if you use Chrome or Firefox. Details at https://privacypass.github.io/ with a bit more of a write-up at https://www.ghacks.net/2019/10/28/cloudflare-release...

That's good to know. Luckily I don't have my own mail server . The Firefox add-in looks like a good idea. Might have to install it, if the captchas don't subside soon. Even Virgin Media has a captcha and they know you are connecting via their network.
