I use it to mean someone who is using multiple accounts at once (so it's synchronic) rather than someone who has had a previous account (sequential). That said, I still use "multi" for people who are making a new account without waiting for their ban to expire or whatever.
So maybe its meaning for me is "alt" with a negative meaning.
R2g was solely a 2nd account and u could not use ur main too or if u did u got banned. But there's been too many people making multis here recently and playing on both at once...
Multi would originally indicate the second, ie someone using miltiple accounts to play at once. I know when I first joined you were limited to just castings so I just made 3 additional accounts and had 4 for my first month.
Starting over on a new account with the former inactive or banned is not a multi.. but over the years the term has been applied in that way as well. But technically that would not be a multi, especially if you’re just using the one and only account
There is a limit of games that can be played at the same time per account, so a person who would want to play a lot would want to create a multi to play more.
Some people do it to play incognito and create some character/fantasy. Some people do it to practice comps. Some people did it to manipulate polls. Some people do it to join the same games and have double the votes. Etc etc.
