Rep has accumulated over the years on this forum. When I joined it took me literally 6-months to a year to gain a full green bar. Very, very few people had big rep power. Most people repped for 10-50 points, 100 if you were lucky.
Now one rep from one person can gain you anywhere from 10,000 to 2/3Million.
It's not about how many times you are repped anymore, it's about who you are repped by,
