Safe bootstrapping

The PoW and some degree randomized PoS blockchain is immune to split-world attack. So someone may ask if so why still some government want to mess with bootstrapping? the answer is to redirect their citizens to malicious nodes and that nodes would associate their usernames (wallets) with clients IP address.
solution:
1- we have a PoW blockchain that full/RPC nodes stores their e-mail address and PGP keys
mining on this blockchain will be rewarded. This blockchain can be only be for bootstrapping purpose
2- Client select one/multiple node and send an e-mail to that node and ask for IP address and wait for signed answer from node
3- What if e-mail service provider acts maliciously and block safe node reply?
the client before logging in to its wallet/username on main blockchain) login to wallet of the bootstrapping blockchain and report the down node incident including e-mail service + VPN/ISP used to bootstrapping blockchain (these reporting should cost users to avoid spam reports)
the accused node either reply to that blockchain that it was online and e-mail provider was responsible.
The user will try another e-mail service and this would also would be a bad reputation for that e-mail service
