I´ve recently purchased some domains and one of them it´s called www.asknasa.com and I haven´t noticed it until I checked it out that I purchased without knowing(it was on my list but I wasn´t going to buy it).
What should I do now?
Ask for a refund?
I mean... I don´t want www.asknasa.com
I don´t want to be sued.
It's only worth what someone is willing to pay. If you paid $5 and someone really wanted it, they might offer $5, or $100, or $1000. I'm guessing they probably won't since NASA is a gov't funded group and would get a .gov address such as asknasa.gov.
