It's actually a well established etiquette on the Internet, or Netiquette as some call it. Chinese forums are different for some reason, probably because most members are younger. But if you post questions to a forum non-Chinese participate in, lack of a name at the end is not polite. See

By the way, please note that many people on this list usually do not respond
to questions posted by anonymous parties. Myself included. In the future,
if you want help, please have the good manners to identify yourself. At
least be good enough to provide a name more meaningful than "anysql".

Some people use forum signature to automatically sign at the end to save typing. You can do so too.
