I seen a three letter .com go for silly money so I wrote a script that found unregistered domains that are four letters or less and registered a bunch of them.
Haven't sold any yet and they are completely random like tqzo.com just short. I used ovh.com because they are cheap and offer free privacy protection.
In the past I have also used godaddys domain backorder to grab expiring domains.
It turns your un-used domain names into a fully automated content aggregator (think of Reddit, but automated) - for those who might be interested.
But my problem is that I never did anything with them...
I previously owned:
NeverEndingSex.com in early 00s -- and I should have made a porn portal... (the domain was bought after the radio piece aired "the never ending sex.com battle".... That could have made a dime, but I was averse to profitting on porn... OnlyFans anyone? (plus I was blocks away from the Armory in SF...
I sold one domain for ~$1500
lost a bunch of really good ones over time... but I have registered hundreds - but never really did anything with them and let them expire.
Goal = 3 to 5 domains with real active projects.
But in the meantime, it just redirects to A Rick Roll
mostly around one set of naming ideas.
bid2{idea}.com - mow, clean, roof, bid2code.com, bid2design.com etc.
and
scan4{idea}.com - scan4rates.com, reviews etc.
and
4{idea}tips.com - 4hometips.com, 4moneytips.com etc.
All Godaddy
Too much drama to try to keep them in diff places
I think they're expensive
Especially if you're not trying to make money with them
