When I played poker my group of friends would split the pot between the two tied hands. We made no distinction between natural and hands with wild cards.
The wiki has it right; not used in public poker rooms but not uncommon in home games as a house rule.
The only wild card games I’ve ever seen in public cardrooms are draw games using a Joker and there is no distinction in hand rank between wild card hands and natural hands.
Home games might have all kinds of wild cards, deuces wild, one-eyed jacks, follow the queen, etc. It doesn’t really matter what the tie breaker rule is so long as it is consistently applied … probably best to just follow the local custom to keep the game friendly. If you are new a group, ask about the rule before you get involved in a monster pot with a fistful of wild cards.
