you will be surprised at how many users connect with blah.tf in their names, its not just scrap.tf. .com is also a common and is actually a group that started from getsome. they have also been affected by this rule.
and yes we know scraptf is not a link, but we know what it stands for, there's no point trying to pull the wool.
We like people to use the GS tag in their names, but we do not enforce it on our admins/mods, any website that you or anyone for that matter, may moderate on, should never have these as a rule to have in your name.
feel free to have geel discuss this with courpse or myself if you think you are hard done by, but rules are rules I'm afraid.
