Olivier Lafontant of Pitchfork compared Echols's mixtape Studio Addict to the early work of Young Thug and Ken Carson.
Echols went under fire for allegedly trying to groom a then-16-year-old girl in a text message while pretending to be a 17-year-old when he was 19. He admitted to these allegations in the song "Clout Demons", saying "I know I fucked up, I admit I was horny..." and compared the controversy to XXXTentacion's.
