My BAD experience with freenom.com
I had some domains registered at freenom.com
1 domain was taken from my account after about 3 month, and was pointed to random advertisement sites.
Another domain was removed from my account after about 7 month and is now for sale at freenom.com. It was not heavily used (about 5 hits a day)
If you your domain is not used many times, then you will be lucky to keep it for 1 year. But don’t forget to renew your domain in the last 2 weeks before expiring or you will loose your domain.
So it looks like freenom.com only gives out free domains for a short period of time.
I will move the remaining domains I have with them to my own domain where I will create a few more sub-domains.
This will be the only possible way to know that your site won’t disappear from the internet.
