So that MODS will be responsible for their actions and avoid unsubmmiting memes without any reason...

Another mod or owner in the same stream would be able to see what they did

Some owners aren't responsible enough or don't have enough time to check that thing and not everyone use Imgflip on a daily basis...

True, but they should be able to remain anonymous if they wish

That's the point, other MODS edit submitted images without any reason, and if they remain anonymous, there's a possibility they will edit it carelessly. If your point is MODS will be bashed because they unfeatured their meme, Just remember that you have to check the box saying that MODS can unfeature memes if they think it's against the rules...

People don’t even look at that box they just click it, when dealing with real problems sometimes it is better to remain anonymous because trolls may target the mod

Because other MODS edit submitted images without any valid reason and I already experience one...

That’s already a feature, you need to be a mod to see it by checking approval history of the image.

I mean, You as the creator of the image should see who edit your submitted image, Because today, only MODS and OWNERS can check the approval history...
