This is more in-line with best practice. Allowing blocking of users facilitates preventing harassment, and allows the user to have more control of the content they see.
This ticket seems to mix several different things (block people who harass versus filtering content that you want to see). This ticket does not describe an underlying root problem but a potential solution. @Quartz: Please see https://we.phorge.it/book/contrib/article/describing_problems/ and improve this ticket - thanks.
