I don’t know.
Age is of no concern here as long as you over the age limit that the TOS state which is 13.
If a user here wants people to know their age they will put it on their profile and if it is not there then they don’t want it to be known.
I am sorry if someone is not talking to you, maybe they are away from the computer and not there to see your messages.
If someone is not talking to you then there must be a reason, if you ask someone else to talk to them that will only enrage any issue that maybe there.
Shadow is a nice person and would not stop talking to anyone without reason, maybe just leave a simple “Hi, are you ok?” and then wait untill the reply.
