It is ok to ask the website to stop publishing this, but since it can be published on one website, it can also be published on another website. If you can stop one, you can't stop many. This method will treat the symptoms rather than the root cause.
It is even more unreliable to set up a mobile phone firewall, which can only block strange numbers. The question is whether all the strange numbers are those things. What if a customer or colleague changes his number and calls you? Isn't it delayed?
The simplest and most helpless way is to change the new mobile phone number, and don't tell others casually. When you change your mobile phone number, see if there is any way to find out who did this immoral thing. The first problem to be solved is not to let this kind of phone affect your normal life, so you'd better change the number immediately.
