Interesting. I looked for evidence supporting your claim and found this: https://github.com/keybase/keybase-issues/issues/3442

It's a very awkward thread where Lucky225 accidentally demonstrates that he has indeed taken over Adrian Lamo's email account. Note this doesn't say anything about whether they were or weren't friends. They definitely had overlapping interests.

Lamo died in '18, comment is from '19.

Sure. Does that indicate whether the account was taken over maliciously or sincerely?

Is your assertion that Lucky and Adrian and no relationship and he had no right to assume stewardship of his online accounts after his demise?

Yes. I know Lucky and I knew Adrian. If Adrian wanted Lucky to assume control of his accounts I’ll eat a hat.

I knew Adrian but I didn't know Lucky. Adrian was always good at compartmentalizing his relationships. Why don't you think he'd want Lucky to have them?

To be clear, they definitely knew each other, I just don’t believe Adrian wanted Lucky to be custodian of his accounts.

Lucky would criticize Adrian behind his back all the time, and Adrian knew about it. They were rivals at best, and frenemies who barely tolerated each other in public at worst. Lucky’s the kind of guy who’ll toss someone right under the bus as soon as they’re no longer useful to him, but feign friendship until then.

I know they knew each other, but I can't speak for the quality of their friendship or Lucky's character in general.
