If there are other sites with no limits, they may eventually get swamped with quickies, with people dumping several images per day. Then they are forced to cut back because they can't afford giving away several gigbytes per day of bandwidth. I wish I had a peseta for every site that has gone under due to bandwidth costs - I'd be one hombre rico. But seriously, I'm pleased with the restraint people are showing. With 100,000 artists here, they could be swamped out if everyone posted one per day - meaning 100,000 images per day. But they're actually posting much fewer than that - more like 200-500 per day total - anyway, it's less than 1,000 AFAIK.
