Why would they buy it? They can just go to a court and get this domain for a few dollars - just like microsoft.com took over mikerowesoft.com
Keep in mind that if you buy this domain name LBC can take it from you at any time.
Possible, but unlikely. Other variations of Localbitcoins.com (e.g. Localbitcoins.org) don't seem to be owned by them. If someone tried to put up a confusing website at Local-bitcoins.com and it became popular, then it could get shut down but I doubt they would bother if the domain was simply parked. Same deal with Mikerowesoft.com. Had it simply been a parked page, Microsoft wouldn't have cared. But in that case, it was an actual website.
And it would cost WAY more than a few dollars to get the domain. The cost for filing a UDRP is approximately $1,300 and that's not including attorney fees.
EDIT: I see chmod755 has already mentioned this.
Yes of course, sometimes people will accidental put this. I believe localbitcoins.com has other domains pointing, maybe old companies they owned and lost. Can someone remind me of any domains that point to localbit coins.com?
Localbitcoin.com, Localbitcoin.co, and Localbitcoins.co all redirect to Localbitcoins.com.
