This account was made because Instagram updated their logo to make it look more modern. The other plz accounts have the old one, so that's why there's this one right here:
You may use it on your profile if you wish. All you have to do is type in ;iconinstagram--plz; but with colons instead of semicolons. I used semicolons as an example, just so you know what I mean. I hope many people will now use this account's plz icon now that it was made.
