How are you?

I'm coding a Discord bot and I'm making a message leaderboard command, which displays up to 15 members with most messages (quick.db package to store data). Basically, It's alright when I run the code, but when someone who has so much messages and should appear in the leaderboard leave the server, it returns an error when I try to get the members tag and undefined in the message.

Is it possible to hide the user or delete them from the database?

What have I tried to solve the problem?

I tried to read Discord docs. and quick.db package to see if I can delete the user when they leave (using guildMemberRemove event), but what if they get back to the server? ﾠ
