my friend tried to ask a question in english.stackexchange site but it seems that there is a problem with his question, the message was : It does not meet our quality standards
BTW the question title was "what is the plural form of the word ( past )".
Asking a question into which time has been invested that adheres to the rules of English syntax will fix the problem. The filter checks for proper punctuation, capitalization, and clear formatting, along with a variety of other things. A clear question will be let through.
Ask your friend to look in a dictionary instead of posting simple questions that waste our time because the answers can be easily looked up. For example, see Wiktionary.
