  34 <PRE>I will fix this problem soon. Removing support for /JOIN 0 from the ircd
  35 source is just not a viable option. There are far too many ircd variants out
  36 there, and this is legacy code. We just have to go with the flow. Besides,
  37 it's not that hard to implement.

  50 </I>&gt;<i> About ircd with JOIN 0 support and services not supporting it, this should
  51 </I>&gt;<i> be considered a major security problem because it can block some services
  52 </I>&gt;<i> functionalities and also serve as a DoS for services
  53 </I>&gt;<i> explaining:
  54 </I>&gt;<i>     a bot programmed to join form chanell #a to #zzzzzzzzz, using join
  55 </I>&gt;<i> #a,#b,#c and then join 0 .... can in a couple of hours disable mlock and
  56 </I>&gt;<i> keep topic functionality for several hundreds of channels, until the bot
  57 </I>&gt;<i> quit's or the services are restarted, anyway for every channel
  58 </I>&gt;<i> the bot joins
  59 </I>&gt;<i> the channel is created on services internal channel list, so it will
  60 </I>&gt;<i> sequentially  memory and slow down findchan function a lot
  61 </I>&gt;<i> because there are
  62 </I>&gt;<i> much more channels to search on.
  63 </I>&gt;<i> My opinio is the best way to fix the problem is not to code join 0 in
  64 </I>&gt;<i> services but take it out from ircd, since most of users don't use it, and
  65 </I>&gt;<i> this way you save ircd cpu insted of using more cpu on services :)
  66 </I>&gt;<i>
  67 </I>&gt;<i> Just some ideas
