Traps:

http://svn.code.sf.net/p/rathena/svn/trunk/conf/battle/skill.conf

// Should traps (hunter traps + quagmire) change their target to "all" inside gvg/pvp grounds? (Note 3)
// Default on official servers: 1 (for players)
gvg_traps_target_all: 1

Frost Joke:

http://svn.code.sf.net/p/rathena/svn/trunk/src/map/skill.c

int skill_frostjoke_scream (struct block_list *bl, va_list ap)
{
	struct block_list *src;
	uint16 skill_id,skill_lv;
	unsigned int tick;

	nullpo_ret(bl);
	nullpo_ret(src=va_arg(ap,struct block_list*));

	skill_id=va_arg(ap,int);
	skill_lv=va_arg(ap,int);
	if(!skill_lv) return 0;
	tick=va_arg(ap,unsigned int);

	if (src == bl || status_isdead(bl))
		return 0;
	if (bl->type == BL_PC) {
		struct map_session_data *sd = (struct map_session_data *)bl;
		if ( sd && sd->sc.option&(OPTION_INVISIBLE|OPTION_MADOGEAR) )
			return 0;//Frost Joke / Scream cannot target invisible or MADO Gear characters [Ind]
	}
	//It has been reported that Scream/Joke works the same regardless of woe-setting. [Skotlex]
	if(battle_check_target(src,bl,BCT_ENEMY) > 0)
		skill_additional_effect(src,bl,skill_id,skill_lv,BF_MISC,ATK_DEF,tick);
	else if(battle_check_target(src,bl,BCT_PARTY) > 0 && rnd()%100 < 10)
		skill_additional_effect(src,bl,skill_id,skill_lv,BF_MISC,ATK_DEF,tick);

	return 0;
}

del code:

	else if(battle_check_target(src,bl,BCT_PARTY) > 0 && rnd()%100 < 10)
		skill_additional_effect(src,bl,skill_id,skill_lv,BF_MISC,ATK_DEF,tick);
