1) I could be wrong on this, but I don't think it is possible to remove participants and assets from the blockchain. A distributed ledger is an append-only system. In a permissioned blockchain, you would simply remove the ability from a participant to make any sort of transactions.
2) This error should appear in the buyingRealEstate function. We check if the buyer has enough funds to pay the other participants.
3) I'll see what I can do :)
For further actions, you may consider blocking this person and/or reporting abuse
