Since you haven't told us what coin this is, we don't know what the rules are.
Actually he did in post #4

Was trying to find out how the guy is doing this without any success, this is just driving me nuts.
He has more hashrate than you and is mining more blocks than you in some period of time but he is not broadcasting them or network has issues with data progagation. Then he broadcasts all new blocks or network data propagation improves somehow. He is possibly an owner of all full-nodes on network except yours so data propagation is up to his likings. But in any case, he has more hashrate than you.
What doesn't make sense is that even if he had more hashrate than me, he would find the first block faster but then difficulty would adjust right away and finding the next block will be equally as hard as finding it in my chain (yes thats how broken it is) and then it is only a luck game.
Total difficulty is higher on his blockchain. The rule is that blockchain with more work done (total of all shares (hashes) which were used to generate blocks) overtakes and becomes valid one.

So on this alt, difficulty adjusts after each block?
Perhaps he has a modded octocoind that doesn't adjust on each block? So perhaps he just mines a long chain without broadcasting it and without the difficulty readjustment, then broadcasts it which orphans everyone else's blocks? Higher hash rate, greater total difficulty, he wins?

- Made a separate network that gets connected to the mainnet once every few hours, and this also didn't help !!!
He has more hashrate than you and is owning you using the same trick as stated above.
How can someone achieve that? I am running a pool which represents 70% of the coin's network hashrate, I can find few sequential blocks then this miner will mine the next block and orphan all of my previous blocks.
Additional information:
- My blocks are broadcasted/propagated normally (checked that)
- Changed IPs, Changed daemon versions and nothing helps
- Made a separate network that gets connected to the mainnet once every few hours, and this also didn't help !!!
How the heck did this miner achieve this and what can I do about it ?
