No, this script does not try to "exempt the netsplit users rejoining channel"
I'm really not sure what would be the best plan to do such exempting.
I could use some advice on ways to pull this off, any suggestions would be much appreciated.
What's the logic behind a script to stop the join floods? Let's say 30 bots join and at the same time some innocent user. How do you differentiate between them? Or you simply just ban them all?
Won't a script that's setting an "active" channel limit put a foot on the neck of a botnet trying to join the channel and thus limit the damage?
Once the game is over, the king and the pawn go back in the same box.
Oh so true Caesar, on both of those points.
I would never run a mass join flood script on any of my channels.
There are other better ways of handling such problems.
I am just trying to build this script for the multiple requests...
gamble27: After more research, no further coding is required to "exempt the netsplit users rejoining channel".
Eggdrop already differentiates between joins and netsplit rejoins.
The amount of time Eggdrop waits for a user to netsplit rejoin is controlled by the Eggdrop config setting: wait-split
When using this script, or any join flood script, be sure to set wait-split to 600 seconds or larger than the longest split on your network.
most mass joins are done with botnets and depending on traffic one can adjust the config setting for it or/and make use of some sort of chanlimit and since bans are temporare innocent ones can rejoin anyway after bantime
if there are other ways of keeping botnets out im curious to know as i tested it in many configurations
regarding netsplit since netsplit shows in quit messages of the unlinked server one could use that to store with a timer and halt this script ( on detect in the quits script )
this is how i would do in an msl script i lack experience in tcl to convert
I have a new setting and the new supporting code that needs testing please...

tested it on testnet and it works like a charm insanely fast, once again excellent release SpiKe^^ thnx for the workz im sure it will benefit many if they are aware of it keep up the works
i found this tcl from user for banmasks i was wondering if it could be integrated (and if so how) to achieve the banmask for the anti massjoin tcl to be in the form of :
