Why is signature "vendor" editing so selective?

My sig went bye bye :frowning:

So since I “obvously” can’t have an actual link to the website, or my email address anymore … Can I at least put the name “Keystone Diesel” back in there? … I have no point what so ever paying to advertise here, there are really only two of us on here that are into performance diesels … Myself and Caleb … and were both from the shop sooooooo
