Conclusion from the replies:
LBC is "half honest" site as they are looking for badly created (I guess not cryptographicaly safe address) addresses which are much easier to find.
Good news that properly generated addresses should be still safe as hell (and I assume Core does use a good RNG).
Thank you all!

There's no way to know whether they "found/collide" their own Bitcoin, unless people report they lose their Bitcoin on 100% offline device and physically secure.
But i wouldn't worry since 2^160 of possible Bitcoin adress take very long time to brute-force (ignoring Quantum Computing in this case) and your Bitcoin should be safe unless the wallet has poor PRNG(Pseudo Random Number Generation), CMIIW.

These people aren't after other people's bitcoins specifically, they're after "special" addresses that were generated oddly.
The transaction they're claiming from looks special to me. I don't know much about it but it looks like it was designed to be found, called the puzzle transaction and all. Also, that transaction is over two years old, so they would have had to plant that a long time ago.
Basically it looks like they're searching for "weird" addresses.

Hi Guys,
I found this site:
https://lbc.cryptoguru.org/
They are trying to ("re")find as far -as I understand- colliding Bitcoin private keys already used and take the balance.
(and they say they have found a few)
My question is:
How do we know that what they claim to be found was not generated by themself earlier and just declared to be found?
I understand that their pool gives out the job, so honest clients will get real work and won't find anything. But bad actors can start to search a given range in which they already have a key in than declare that key to be found.
Thanks
