Ok this is a script that converts bad words to censored. Just copy this into your remotes (Alt+R). If you wanna block more words just edit it!

  if (shit isin $1-) || (bollocks isin $1-) || (fucking isin $1-) || (fuck isin $1-) || (crap isin $1-) || (twat isin $1-) || (cunt isin $1-) || (bitch isin $1-) ||  (motherfucker isin $1-) || (wanker isin $1-) || (pussy isin $1-) || (dick isin $1-) || (dickhead isin $1-) || (ass isin $1-) || (asshole isin $1-) || (gay isin $1-) || (lebian isin $1-) || (lezbo isin $1-) || (lesbo isin $1-) {
    .echo $chan < $+ $nick $+ > $replace($1-,shit,<censored>,bollocks,<censored>,fucking,<censored>,fuck,<censored>,crap,<censored>,twat,<censored>,cunt,<censored>,bitch,<censored>,motherfucker,<censored>,wanker,<censored>,pussy,<censored>,dick,<censored>,dickhead,<censored>,ass,<censored>,asshole,<censored>,gay,<censored>,lesbian,<censored>,lezbo,<censored>,lesbo,<censored>)
