Probably worth remembering the adage:

'The internet is forever'.

... I can also tell you that there exists.freely available tech, that anyone with sufficient know-how can use, that can turn a 2D image into a pretty darn accurate 3d model... the versions of this that you pay for, well, they're even higher fidelity.

I've been using versions of this kind of software to help me with modelling a morphable face mesh I intend to use in a video game to make some reasonably realistic presets and basically character creation sliders.

Its the same tech that biometric recognition is built off of.

Hence my earlier advice of trying to make yourself as unintendifiable as possible.

If you don't care, then you don't care, but if you do want to remain anonymous/psuesdonymous... yeah I'm not trying to scare you, I'm just trying to be realistic.
