I just received a message from Lily.com on my mobile phone. What's going on here? Spam messages, harassing messages or ... what's the situation?

No matter what spam messages or harassing messages are, they are useless to you anyway, just consider them harassment.

If you often receive harassing text messages, you can use Tencent mobile phone housekeeper, which has harassment interception function.

You can extract the main content of short messages as keywords and turn on keyword interception.

So you won't receive a text message containing these contents.
