Question to new IP Address Blocklists

Actually it is two questions, the new feature of address blacklists is actually the same as the lists from the IDS rules, or am I wrong and it is an additional feature? Where exactly is the difference the origin seems to be the same?

Second thing all the messages from the blacklist are nicely displayed in the log, there is even an extra menu where you can look at everything in detail, but why please the kernel log is overloaded with it in the overview and there was no extra point created. The kernel log of the gui has become completely unusable from the flood of messages that arrive there, can not design it differently?
