Lol, don't have to
site is for convenience. Hate charging but back in the day when I had ads (literally ONE ad) to try to cover hosting/server & domain costs but then people decided to block my one ad, so then I had donations and after three years I received 50$ and had roughly 4,300 users, and 720$ of my own money I put a fee on there to cover my time, hosting, domain renewals, upgrades, etc but hey if 5$ is too much to keep a site running and my site dies down then I won't have to pay costs any more because I can shut it down(while retaining the domain names).
So hate it if you will but the code behind it isn't writing itself
Sorry for late reply, I generally do not use this site that often.
