I don’t know if this is still the case, but I am convinced that, years ago, when you searched for an available domain name, somehow someone knew and they registered it for speculation. Because of this thread, I wouldn’t be surprised if C3.band has been snapped up. If not, register it now.
This does in fact happen, and sometimes even happens directly from the domain registrar. I lost out on a domain a couple years ago because of this - looked up the domain I wanted and it was available, went back under a week later and the same site was now asking 10x the price.
Ahh, but is C3sus#5#9#11.com available?
Indeed, but you also need to prove that "the domain name registrant had a bad-faith intent to profit from the trademark". That may be difficult.
