I would like to point out a few syntax errors in the published description or expressions whose meaning most likely departs from what was actually intended.
1
We will not give away your email address to anyone, who is not related to the operations of ruby-lang.org.
The comma between "anyone" and "who" indicates that the relative clause "who ..." is used in the non-restrictive usage. In other words, this sentence means:
We will not give away your email address to anyone (at all). (By the way,) No one is related to the operations of ruby-lang.org.
Most likely, you intended the restrictive usage, in which case you need to remove the comma.
2
... we use those files for debugging and statistical purposes.
This sentence may imply that ruby-lang will use those files at least for debugging and statistical purposes, and may (or may not) use them for something else. It does not guarantee anything about privacy.
I think what you intended was:
... we use those files only for debugging and statistical purposes.
3
Please refer Usage limits of GitHub Pages.
You need to insert "to" after "refer".
4
In the above, you have "Usage" and "Pages" capitalized, which suggests that the phrase is an exact citation. However, what seems to be the corresponding phrase in the linked page is:
Limits on use of GitHub Pages
which is different. You either need to replace "Usage limits of GitHub Pages" with the exact phrase as above, or spell it in your own words without capitalization like "the usage limits of GitHub pages".
5
Some sites under ruby-lang.org (e.g. bugs.ruby-lang.org) uses cookies to keep track of user preferences.
You need to replace "uses" with "use".
