I often see U+FEFB and other lam-alef ligatures used on social media (I easily spot it because my default font does not have them so they end up using fallback font). My guess is that might be because some keyboard layouts (Xorg, Android?) use them for the lam-alef keys on the keyboard (I’m guilty of doing this for Xorg keyboard layout because it didn’t handle more than one character per key, this was then decomposed back inside XIM input method, but many people don’t use XIM and the decomposition does not happen, it was messy overall).
