[BUG] List of blocked domains is too large and saved in an option that is autoloaded which slows down your site

[jmslbam]

Hi all!

After importing the recommended settings a site becomes slow because the autoloaded options will grow with 2MB.
I have had this kind of problem with other sites that stored to much of their data in an option.

To Reproduce
Steps to reproduce the behavior:

1. Go to MySQL and check the sizes of the zero-spam-settings options that is Autoloaded.
2. Go to Use Blocked Email Domains Recommendation and import recommendations
   
3. Go to MySQL and check the size again. Mine grew by 2.1MB, yupp that's right 2.1MB extra on every load from the Database.

Expected behavior
I expect this large of amount of data not te be autoloaded and to be saved in a separated table.

Thanks for bringing this to our attention @jmslbam. This problem is a little more complex to fix, but do have plans to rework the settings system to avoid this. I'll leave this issue open until that has been done.
