would it be possible to create a module or configuration that hides the message Message blocked: Spam / advertising so that the offender does not look for alternatives so fast?
instead of block action, you can chose shun, which is not shown to the user, or if you want to block only, change the reason to something else instead of "Spam / advertising"
thanks for the answer ... I already try to do that but the spamfilter does not allow adding filters for no reason or just fill it in with spam / advertising .. I looked for the forum and found a module that Gottens did which supposedly does what I need but I did not find it
