Hapo hufuti chochote, unajiondolea access tu. Do you remember back in 2008/09 were if you deleted your profile and then typed the exact address of your ID you could see your data? Facebook went on and fixed but it exposed them that data is never permanently deleted, all they do is just blacklist it that no one can see it.
However old your data is; it will prove useful to agencies that buy it to sell you ads, and governments to spy you.
The only way to remove your online presence(from now on) is by not using the internet,smartphones etc like Richard Matthew Stallman a.k.a RMS but the your past online presence is there to stay.
