Question for you, please;
What is your current favorite tool for checking
a domain name’s history whether there’s been a pre-existing site or not (like only an affiliate redirect), for researching whether it’s ever been banned, blacklisted, or otherwise slapped by Google etc?

I know there are numerous methods/tools/services,
but as a value to your readers,
what is your must have/ bottom line choice?

[This subject is probably even worthy of its own post]

Thanks a lot mate,
Ed
