When hosting, the less maxclients you have, the more stable your server will be. I haven't really seen any random crashes/masspings at below 20 maxclients, and they used to be rarer with 25 or less (though it's supposed to be stabler now, is it? - I have no idea, I don't risk it). Additionally any mass commands like muteall or specall can induce a lag. /fuke is risky as well, especially when abused (e.g. executed several times in a short timeframe).
Additionally if you have proper screenshot evidence and your room dies within like 15 minutes since your first global, you can ask staff for some assistance regarding this situation (e.g. you might get a free global for remade room), preferably by going to #support on irc.
