It depends on who is asking for help. If that person is deserving, and just going through a tough phase (lots of hardworking people out there without jobs) I’d say there’s no harm in helping. Agar aapke haaton kisi ka bhala ho raha hai to why not? But also keep in mind that if you recommend person, YOUR (or your parents’) credibility is at stake too. So be careful who you recommend.
Of course if this guy is a “leechar” as Nomi said, just ignore them!
