Someone I was living with at the time told me(collective housing) and said things that no one could know unless not only my browsing history was being watched but also everything i wrote on the computer or phone and the camera being turned on. They didnt want to reveal where it was being shared though, just that it was being shared and i have moved out of there now
When living in a communal setting, I can think of a number of scenarios where your data could have been compromised.
Assuming that what you are being told is true, you should be concerned that your computer may have been compromised unless you have done a totally clean reinstall of your OS. If you have, did you also restore a backup of your data? If so, you want to be very careful that you do not restore any program or utility that would recreate the very same attack vectors. I would strongly suggest that you have the computer interrogated to be sure that all is now well.
