Leakers need to understand something.
No single human being walking on this planet Earth in the year 2019 has a camera that produces blurry pictures. It just doesn't happen.
I get that it is much easier to spot flaws when things aren't blurry, but a blurry image is one giant flaw in itself that immediately gives it away as fake, no matter how well done it may have otherwise been.
You need to take that extra step these days to get tricky with it. If you can't find a way to lay a fake leak without the blurr, what's even the point? All your hard work will have been for nothing. You've gotta try something plausible on all levels.
And hell, if you can't do that, you can still post them as Fakémon online from the start. A lot of these fakes are very professional and look akin to real pokémon. They'd be some well-loved fakémon if they weren't falsely touted as leaks.
