Erasing Skin on purpose

In Minecraft Pocket Edition, this is a serious issue and people might/will take advantage of it. When I used a skin of Obama I notice that the invisible spots of the skins did appear on the servers and normal games, then I thought of erasing the rest of the skin and leave two pixels using an app for Minecraft skins and it actually worked too. I was invisible, I joined an online game and I crouch for the rest of the game, no one notices me (I was hidden because I could see my shadow so I hide so people wouldn't notice me) either way, I won the game and I think this should be fixed before someone else does this and doesn't report it, Here are some pictures to be more clear...

Btw this in on Minecraft PE version v1.14.30

I have a picture of someone already using this "glitch" and it needs to be stopped now... plz...

Thank you for your attention.
