From IFAB laws of the game,
- LAW 7 - THE DURATION OF THE MATCH
- ABANDONED MATCH
An abandoned match is replayed unless the competition rules or organisers determine otherwise.
However, laws of the game does not mention how the result of game should be recorded. So, it is up to the organisers (or, from competition rules) to decide whether or not to replay the match, and if match is not replayed how they want to keep this in record .
[Note: These abandoned matches examples are not because of red card limit]
Result after abandoned match depends on competition, Football League decided abandoned match of Blackpool v Huddersfield Town as draw whereas there are many cases of match being decided as 3-0. Few examples of such are,
Albania were awarded 3-0 win after Serbia match abandoned over drone stunt
Malmo awarded 3-0 win in abandoned Gothenburg match
Siġġiewi FC a 3-0 win after finding St George’s FC guilty of causing the abandonment of the BOV Second Division match

From football-stadiums.co.uk article,
In Spain, for example, a match that is already partway through isn’t abandoned, it is merely postponed to a later date. This means that if a game is halted after 68 minutes with one team 3-0 up then it will be resumed at a later date with the remaining 22 minutes played out.
