Crawl.blog is a passion project and is not monetized in any way. Fortunately there are no server costs as everything is hosted by Gitlab <3 for free but there are time costs and I can't afford to write as much while having full time job and part time activities.
If you would like to support this blog there are few things you can do. The best kind of support would be contribution, either by providing ideas for new articles or fixing mistakes; check out source code page at the footer.
If you wish to support the page financially you can check send me some crypto:
Other than that you can hire me for freelance web-crawling or teaching :)
