That will never happen. The reason being stated plenty of times over, |
40 |
but I'll state them again: |
41 |
|
42 |
* Many of those addresses are from dynamic IPs |
43 |
|
44 |
* Some may be using fake IPs that you login from, it would suck to have |
45 |
you banned from your own server |
46 |
|
47 |
* if anybody can submit to an RBL you would have the whole world added |
48 |
to that RBL in no time because somebody will get the bright idea to do so. |
49 |
|
50 |
In short, bad idea. |
