Just Realized: Is Alma actually Alice_Rabbit?!?!

[Pebbles]

When she hacks the bar station to serve Jill drinks, a short glitchy screen of a toy rabbit was shown. If you serve her the Flaming Moe, the hacker from ROM shows up looking for trails of Alice_Rabbit. Also Alma insists on convincing people that Alice_Rabbit is a group than a person.

So is she Alice_Rabbit? or maybe a member of it?!

[(ᵔᴗᵔ)]

I don't think there's enough clues to definitely say whether Alice_Rabbit is more than one person but as you've said everything seems to point to Alma being at least a member.

After seeing the end of the epilogue I also have my suspicions towards Anna but that's more of a long shot.

I think she is. She's pretty cool

When Alma hacks Jills phone and gets her pictures of Dana, at the end of the day in the room it says Happy not-Birthday in hacker style, and in danger /u/ they mention something like that

With what Alice says about it not being one person and comparing it to the Anonymous group, I think she was the original Alice_Rabbit but more and more people started claiming the name when hacking and now there are a ton of copycat Alice_Rabbits on the internet. At this point it isn't even one cohesive group, it's just a banner any hacker could use for attention.
