Contrary to what the trolls above might think, it’s due to the number of threads. The cred bonus is 20% of the regular cred issued per thread and compounds with each thread that you pwn in a row.

So Cosplay Central gets you 583333 per thread base with a bonus of 116666 at a max of 12 threads.

1: 583333
2: 583333+116666
3: 583333+(116666*2)
4: 583333+(11666632)

Eventually works out to a max cred of 14,699,992

Looking at a level 55 forum in the storyline gets you 750000 base and 150000 bonus with a max of 9 threads. Follow the formula above and it works out to 12,150,000 cred total.

Why aren’t the higher level forums vastly more cred than the level below them like ep 1 and 2? Has to do with the level scaling. From level 36 to 69, the cred gain required is the same as the previous level. It doesn’t make sense to have forums giving out hundreds of millions of cred when it only takes a fraction of that to level up.
