!ignore is absolutely not usable here, sorry rasz.
/ignore would be the way to do it.
!commands are (as i understood) commands to be executed by the server and in this case it would mean _heavy_ patching of the server as the server has then to keep track who is ignoring whom.
Where as
/ignore is the client-side command that eould tell the client to drop pmsg from a specific player. But that would mean an unpure client.
here, read once more what its about :
I don't know if this is in the right forum, but here it is anyway.
Is there a setting to stop players disconnecting you from a server by essentially spamming a message from them, which does not show up as normal chat, and this spam disconnects you from the server within a couple of seconds with the 'ping too high' error.
TIA.
Hi
Since yesterday such a kid is sitting around on the Corbina Server. Deconning and spamming via private message. Some of his victims get a "Server Command Overflow". I don't, i guess its because I'm using a "new" client...tjw from november I think. Nevertheless, his spam causes me to lag.
Is it somehow possible to just turn off these private messages?
If not, it may be possible with a patch like this here:

But, would this also avoid the lagproblem.
no, lag would be there 
LAG, its about message spam LAG, must be server side
!ignore is absolutely not usable here, sorry rasz.

yes, just like /share..
but this is the GAME, game for the PLAYERS, and PLAYERS dont give a F(udge) about server/client side, they want to do !help and see "oh, i can share and ignore ppl, kewl", they dont want to guess what commands are available to them.
as a last resort /ignore and /share syntax should be in the !help menu to actually HELP players use the game.
btw
https://bugzilla.icculus.org/show_bug.cgi?id=2811 needs a client side argument/switch, i dont want to be forced to server settings like on the R1CH builds (try to tell your team 3 things fast, yep you cant, server cuts you after the second one), i want to decide who I ignore, and what is a spam to me.
