Good links TygerTyger, however this seems to be put in place to stop short time domain registration for spam. I presume the first thing checked would be the domains history, then, if it's a new registration, look at when its been registered to. Effectively it seems to be a tool to check newly registered rather than established domains.
Looking at when Nutstretch registered on these forums, I pressume the domain has been established for a while, therefore has a history. If it is an established domain it was very, very poor advice to give. Seems to be a case of a little knowledge.....
(If it isn't an established domain a little slice of pie is at the ready
)
edit:
Actually for an established domain it's not just very poor, it's just plain wrong and even if it's a new domain it's still very bad advice. Even if there is an effect, all you need to do is register it for more than the minimum. Definitily a case of a little knowledge.....
