Depends on the request of the person. The time I offered free rituals, and it’s only been once, I was looking for things that the magicians had already tried everything they knew, and still had not obtained their goals. I asked for the impossible things. I also offered servitors when I this did. I ended up taking nine individuals requests and all but two received either what they requested, or reported that their servitors made a notable appearance when they attempted to summon them.
Possibly, but quite simply, I think many are too pompous to believe that they could find themselves under attack by such things. Others think simply that a few replies or thanks you’s means the magician must know what they are doing. Sometimes drug use or mental illness and delusions are an issue. But most often, I think it just doesn’t seem like an interesting topic, I’m not offering anything but my own opinion here, and well that’s rather boring, is it not?
At least to the newbie, who just wants to get right to summoning demons and angels and all sorts of spirits, with no notion that things could go awry, because they haven’t put in the time and effort to comprehend that magic doesn’t just work at a snap of a finger. I see a lot of people that have be warned about possible consequences and they still don’t care, but they see so many posts about how someone summoned this amazing spirit on their first try and all their worries were just wiped away within a blink of their eyes. I find the newbies often have trouble distinguishing between larpers, role players, those that are just plain bat shit crazy and the real deal.
Personal conjecture based on what I see, and I imagine opinions will vary greatly on this one.
