I guess this is a cautionary tale.
I was recently having issues with my Gmail account that's tied to my Epik ( a domain registrar ) account, so when I was supposed to renew my domain, I didn't receive any e-mails about it. When I decided to randomly check on my website, it seemed to be down. So I checked Epik and a domain that usually cost £15 a year to renew now cost £400 to renew as it was expired.
As a teenager who does not have £400 to spend on a domain, I decided to just wait until the domain fully expired and buy it for a cheaper price.
After some time, the domain fully expired and GoDaddy decided to buy it as soon as it did, and charged me £2,225 to renew the domain. I don't understand how a price that large is justified, considering that my website gets barely any visitors and I basically only use the domain for hosting stuff. No idea how hiking prices this much is legal
So search for a lot of domains at random to cost them some money?
Absolutely. But I think it might be more advanced than that. They might have some sort of analytics that measures how long people stay on the page, etc to inform their purchasing decisions.
Ah, so search a couple of domains and sit on their page for a while making random mouse movements and scrolls then? Got it.
Bots would help but have their own problems.
