General reminder:

The domain name putty.org is *NOT* run by the #PuTTY developers. It is run by somebody not associated with us, who uses the domain to interpose advertising for their unrelated commercial products. We do not endorse those products in any way, and we have never given any kind of agreement for PuTTY's name to be used in promoting them.

Please do not perpetuate the claim that putty.org is the PuTTY website. If anyone is linking to it on that basis, please change the link. The PuTTY website is https://www.chiark.greenend.org.uk/~sgtatham/putty/ and it always has been.

You can check this by downloading the source code, which cites that URL in many places (the README, the documentation, some strings in the actual code), or by using the "Visit Web Site" menu options in the official Windows binaries (the ones signed with my personal Authenticode certificate). The true PuTTY website is the one that PuTTY itself says it is.

Many search engines list putty.org above chiark. I don't know if this is due to active SEO on the part of the domain owner, or a heuristic in the rankings. Either way, don't believe them. It's not our site.

@simontatham I think you should absolutely lawyer up and file a WIPO Domain Name Dispute Resolution complaint. https://www.wipo.int/amc/en/domains/

"When your brand is misused to deceive consumers online (also known as “cybersquatting”), WIPO – the global leader in domain name dispute resolution – can help you reclaim the infringing domain name using an online enforcement tool called the UDRP or a national “ccTLD” variant."

@farbenstau @simontatham Typically if brand name is registered after domain, there is no chance getting a domain other than buying it from owner. Unless you can prove your unregistered trade mark is well known and that current domain owner is referencing to your brand and not some similar.

In short, always register domain and then registered trade mark/name afterwards before getting your brand public 

@gytisrepecka @farbenstau in this case it does seem pretty clear that the current domain owner is referring to the same PuTTY I am, and isn't talking about some unrelated thing with the same name!

@simontatham In that case it is more than possible to get the domain
