Rob Kardashian and Blac Chyna's alleged cyberbullying may prove costly ... so claims one of BC's ex's who's suing them for more than $2 mil.

Pilot Jones filed new legal docs saying he's been damaged to the tune of $2,113,800. He says the alleged cyberbullying and defamation caused him emotional distress in the amount of $500k. He also says Rob and Chyna's alleged attack on him fractured his family and he wants $250k for that.

But, there's more. He wants more than $250k for past and future medical expenses and $600k in lost earnings. And, there's still more ... he claims he somehow lost rent and that's another $7,200 and he wants reimbursement for a trip to Louisiana, where he fled back home after the alleged attack.

And last but not least ... he wants $500k in punitive damages.
