Ok, they are .

But thats not the point. The point is that every time I read a thread where the read is "xx/yy fish" I cringe in my seat. Probably the worst read you can have other than no read at all. Identify WHY they're a fish. What traits are they displaying? What patterns do they exhibit? THEN think how you can exploit that.

People post something like "villain was 70/10 over n hands, so I did xxxxx postflop".

Wat!!??

Why are you using a pre-flop read (preflop stats) to decide how to play postflop? Some fish play loose passive pre-flop and then fold to aggression on the flop without the nuts. Some fish play loose passive pre-flop and call down with any piece of the board and sometimes less. You should play completely different against the two!!. That means pre-flop as well as postflop. The hands you play against them, and how you get to the flop with those hands should also change. Play right and both types are free money, play wrong and it could be you going busto.

If your only read is "fish" then you're not trying hard enough, or dont have enough information. Pay attention to the players who seem particularly bad, and identify what they're doing that makes them bad, then exploit that. Dont make the mistake of playing in ways that actually help their mistakes work for them.
