1) Run your own background check and see what comes back. Most will let you run your own check.
2) Don't mention this if you want the job, the the FAANGs did go through a period where they wanted activists / not just the standard coders but I think that might be somewhat over.
3) I would never hire someone with your record if I knew about it.
A note - use straight language if you are committing crimes for moral reasons. For example "defends unborn children from child murders" is committing a murder of an abortion doctor under our current laws, "rescuing animals" may be theft or burglary. "saving the world from GMO" may be destroying a local farm. "saving the world from gentrification" may be multiple arsons (in emeryville for example). 9/11, the US wars in many other countries are often tied to these ideals justify violence and killing language models.
