This does unfortunately actually work pretty well as a security measure. The new domains that are cheap and good for fun side projects, are also cheap for scammers.

For a while I noticed all the scam links my grandmother was getting were from ‘.top’ domains. I fully blocked it at the DNS level. Her DNS settings also block all newly registered sites for 90 days. She hasn’t ever had issues with it. But these have actively prevented her from clicking on scam links multiple times.

Facebook, google, and all the popular sites are all older than 90 days, on popular well known TLDs. My grandmother doesn’t seek out new trendy sites.

It was definitely something I considered when buying a new domain. I sorted by price, and then immediately ignored all the cheapest domains that were ~$1 because I’ve seen them being used for scams. They may be cheap but good luck using them.
