"X" (formerly Twitter) flags the gitbook URL as potentially scammy.

I only got https://ebay.gitbook.io/mindpatterns posted on X using a URL shortener. Clicking the shortened link results in a warning page. When you choose to ignore the warning you get forwarded to the correct page.

Trying to post the un-obfuscated link results in an error.

I imagine it's because of the word ebay in the url.
