If your L thinks finding dirt on OW would help your filing, you need to be careful. Snooping and becoming obsessed with OP risks bringing you down from the high road.
Consider calling a private individual that specializes in such stuff. They already know which cheap internet search tactic works and which ones don't. They also have made contacts in information based places you have no access. Let them give you an explanation of what they do, and charge. Decide if you can afford to turn this over to one of them and step away from it.
It would even be nice if they said I have your dirty details and you could say give them to my L. It probably wouldn't work that way, but it would leave fewer long term mental scars for you. The more investigating you do on your own, the more negative your memories are going to become.
Think twice, step once, think twice again. Take care
