It really depends on what kind of help they are looking for. Of course those asking for gil immediately out of whatever excuses like they can't afford potions for their ailing grandmothers and nothing else will get ignored like how most people here said. I don't mind giving away gils but not to people who wants it right away effortlessly.

However for those who really wanted help in stuffs like their starting classes or NPC/quests/crafts/etc stuff I will spend as much time helping them out so as long as they are interested to know more. Once they're done or have to go, I will ask if they want to add me into FL for future help (Not forcing them to if they don't want it). I don't really mind giving away stuff (not expensive) to help them get through something the first time but anything further I will just advice them how to do it so they actually know how.

I like helping stranger newbies often, since I always forgot what I did on my first day so helping them makes me remember those days.

(For irl friends who just started the game to join me, since they know how we treat each other irl I will usually slap a bag of gil, some gears, on their faces, tell them to figure out everything themselves and then call it a day before heading back into dungeons :U )
