Including board nicks in domain whois details

[Head Boy]

It was more to help get onto a white list than to detect cheaters. The submitter's id is obviously a good check, but I've seen those traded on some boards. I've been thinking that my domains must be difficult to check as I've got several hundred of my own, and I act as an authorised registration reseller to quite a few other webmasters. Many of those don't seem to update their details and leave a bastardised variant of my details there. I used to use "Sex Elf" as registrant, but now I use "Elf Domains", either of those should indicate that it's my domain. My registration service is "Domain Pairs" and I know that some of my clients were being rejected by LL owners until I got them to update their details.

What would be the easiest way for me to make checks easier for site owners?
