Bitcointalk's given opportunities to ppl who couldn't own bitcoins before. Sig campaigns helped ppl to save bitcoins so the forum's helping users grow. We don't know why he's asked for $10 but he's asked for multiple loans it's why the topic's made.
Bitcointalk is a great opportunity for everyone living in a poor country. Anyone who has been in a signature campaign in this forum for more than 3 years is not supposed to be having $2 to $10 challenges. Saving only 10% of ones signature earnings for 1 year + bitcoin price increment is okay to solve minor financial issues.
