When time permits, the IPs that are known spam are researched and banned. It is difficult to do this on a daily basis. It probably is impossible to get rid of all of them. Once a process is put in place to stop them they figure out some other angle to get through.
All we can do is continue to stay ahead of them and delete ASAP. Psychdad PMs a list of IPs to me from time to time and then they are banned. This works well. Most sites with lists of IPs that are spammers do not allow you to copy multiple addresses at a once. If these can be listed for me, it is easier to copy and paste.
Or, if anyone has a site which lists the latest nuisances and they can be bulk copied, let me know.
