Okay, first of all I want to apologise to you. I said that stats were saved locally but I've learned that they are not, they are stored together with the server files but that only makes this easier. I had your statistics looked at and it showed that you had fished a total of 39484 on the green server. Not 7022 fish as you're saying. But you are right that the statistics also include the broken tools and treasure that is part of McMMO. However, at lvl 875 fishing and above it's only a 20,36% chance to get a non fish (see McMMO wiki
http://mcmmo.wikia.com/wiki/Fishing ) which would mean that out of the 39484, about 31445 out of those would be fish.
As for the money, the price gained per fish increases as your job lvl grows higher. These screenshots are taken at lvl 1 fisherman and lvl 50 fisherman and both are while having 4 other active jobs.
As you can see the money gained from each fish heavily increases and you get paid more from catching more rare fish. And its only about a 4/7th chance to get the raw fish with LotS 3 (see Minecraft Wiki
https://minecraft.gamepedia.com/Fishing. Keep in mind that McMMO removes the vanilla chance to get non fish) so about 3/7th of the 31445 fish would be $16 or more (based on lvl 1 fishing).
Now it is possible to simulate the amount of money you would've earned from 31445 fish but to simplify things, we can use the algorithm to calculate the xp required to lvl up the fishing job (see GitHub for Jobs
https://github.com/Zrips/Jobs/blob/master/src/main/resources/jobConfig.yml). The algorithm used is "leveling-progression-equation: 10*(joblevel)+(joblevel*joblevel*4)". Your level before being reset was 72. Using the algorithm we can find out the required xp to reach lvl 72 which is 512904xp. And as we can tell from the screenshots of the jobs, the xp rates are static while the money increases per lvl. At lvl 50 fisherman all the fish grant more money than xp and since the xp required to reach lvl 50 is only 173950xp we can assume that (512904-173950 / 512904 = 0.66) 66% of the fish caught gave you more money than experience.
So, since you've accumulated at least 512904 experience 66% of the fish caught have given you more money than experience I would say it's safe to assume that you have made ~547k (no, not 600k) through fishing, that we removed from your account.
If any of my calculations are wrong, please prove them wrong.
EDIT: And as for your mute, that has nothing to do with the fishing. You were muted because you were harassing people on the server.
