Stop using Senventh's avatar, lol. He has had it way longer than you have, and on top of that, nobody else is using a "spoof" of it. It just shows how desperate you want attention. Hell, even by creating a drama about it, I'm giving you attention. I guess it works. So you can stop now.
I recreated it in photoshop, using his as a base, and then I used custom text to make it my name.
Its just a lowkey blockland meme to spoof other BLF avatars.
