Reinsertion of previously deleted information is only regulated under the FCRA if deletion was done by the CRA based on lack of verification of a dispute.
If its an OC account, I would also speculate that they may have sold the debt, and simply wanted to remove their reporting so as to eliminate any need to update reporting or to investigate any dispute that might be filed.
If sold, you will most likely see the new owner reporting a collection.
You might contact the OC, and if they state the debt was sold, obtain the name of the new owner.
You could then send a DV to prevent credit reporting until such time as they provide validation of the debt, or contact them and make a similar pay for not reporting offer to them. They may be more receptive to agreement not to report than to deletion after they report.
