I spend a lot of time working on creating and running various websites, developing open source projects, and running Telegram bots.
Donations go towards the server infrastructure that runs all these sites. It costs over $400 a year to maintain the servers, domain names, etc. that run these sites.
You can find my open source projects on GitHub at https://github.com/Syfaro or my own Gogs instance at https://git.huefox.com
