Those aren't valid sources, but you do have a valid request. :p For anime we use the English title in the following order:
1. Japanese-English Title: This is where the title is already in english when released in Japan and overrules a translated or renamed for english release title.
2. Official English Title: This is where the anime has been packaged for sale or airing in english speaking countries and is used most of the time.
3. Translated English Title: This can be either a common or sometimes literal english translation of the japanese title as listed on ANN
(both of which ARE valid sources)
The Japanese titles are usually then added as aliases to prevent duplicates from being added.
If none of the above versions of an English title are available we then default to the romanized Japanese name.
Hope this helps. ^_^
