i noticed like for example on dalnet u can use multiple targets for whois command meaning u can compress multi nicks in in 1 whois command (not sure what max allowed is as raw 005 doesnt say on connect i tried like 20 nicks in 1 whois command and it seemed to execute fine tho)
like so: whois nick,nick,nick,nick,nick,nick,nick,nick,nick,nick,nick,nick,nick
wich might result in not gettin disconnected in the case of mass joins unlike having it execute 1 by 1
wich might get u disconnected since using a command excessively in the case of a mass join wich happens regularly on dalnet not to mention the daily netsplits wich has nicks mass rejoin again after servers link again
