No site within the Stack Exchange network will take the (paraphrased) question
Find a way to block a very strange kind of spam?
There is simply not enough information to start answering that, let alone suggesting a site.
Here are your options, if you can narrow down what you actually need.
- If you are looking for how to configure spam filter options in your locally installed e-mail client, research on Super User
- If you are looking for configuring spam filter options offered via a Web Application / Saas, research on Web Applications
- If you are looking for adding spam filters in your self-hosted e-mail server, research on Server Fault
- If you are looking for a plugin to add to your email-client, research on Software Recommendations
- If you are looking for ways to legally stop the spam, research on Law
- If you want to help fight weird spam posted on the Stack Exchange Network, go to CharcoalHQ
None of the sites will take your question in its current form. That is why I stated research in all above suggestions. The minimal research is going over their on-topic page and related material. If you rather discuss the spam and your options, find a chatroom, reddit or Quora. For venting about spam, use Twitter.
