21 members in a public alliance????

Saw an alliance with 21 members.
How is that possible?
Can anybody explain?

Might have been an Alliance with less than 20 members and several people applying for the vacant spot(s)?

You may want to use a more clear, less clickbait-y title in the future.

21 comes from someone applying, like Quebb said.
The extra score doesn’t count for PVE or PVP alliance rankings.

Will this happen to a public alliance?
When i searched the alliance name it shows public 20/20.but when checked the details it shows 21/20.i also counted 21 members.
I am sorry if this a stupid question?

Please some body answer.

I don’t Think you will get a better answer. It’s probably multiple pending member showing up on the members list. It happens sometimes.
