The rates would be same or close to same as now because the rates were probably low back then of BTC, But people who saved all their earning they must be living the life, would be interesting to know though someone who actually joined the campaign should post.
There's a split in the campaigns now, some pay about the same rates as before (slightly less) and other campaigns are paying significantly lower rates, dust by comparison.
I'm surprised the dust pay campaigns are even in business, why people accept these lower rates is beyond me.
The real difference was that a few years ago there usually was no limit to the number of posts one could make in a week. You could make 100+ posts getting paid
BTC0.0007 per post. That's how people were making such a killing!
