Instagram stalking..?

[Josh]

Funny situation..my friend today was stalking someone elses instagram and accidetally like a picture of theirs, now shes mervous be she thinks they know. When you like someones pic and quickly unlike it, I know they see the notification but do they see it when they actually get on insta? Or does it disappear since its unliked?

When they liked it it would show up quickly on the other users account..they could have saw it if they were on..but since they unlikely it they won't see it

It disappears as soon as you unlike it but if they were on they would immediately see someone liked their picture so if they clicked their littler hear button on the bottom they could see (answer mine?)
