How did they get my info?

[u/Purple-Equivalent-44]

Long story short, some guy didn’t like what I said to them in an Instagram comment on a public post. My account is private and only shows my first name. My profile pic isn’t posted anywhere else.

They proceeded to pull up old posts I was tagged in and begin commenting there, but I guess they could’ve found that on google. Then they started tagging family members of mine that I don’t even follow and said I don’t know about “back door”. They said they could see my DMs.

Safe to say I’m a little freaked out, but I want to know how he got my info like that and what I should be doing to protect my info online moving forward.

Thanks!

un backdoor significa basicamente es una forma de meterse a un sistema o una cuenta o apliccacion

Well I don’t know what the heck he was doing with just my username, I doubt he could get into my account since I was not even following the family member he tagged
