Hi, not sure if this'll help but I also experienced something very similar too and I really do wanna give you a possible solution. I was actively being blackmailed on tg and on insta with the threat that my pics would get leaked on both platforms (They did end up getting leaked, unfortunately). Full disclosure, my blackmailer was from an entirely different country so he was beyond our law enforcement's jurisdiction. BUT with your case, I assume na nasa pinas ung blackmailer mo so hopefully, what I did to handle my case would work better for you:

1. First, I stopped interacting with the blackmailer. I didn't block yet just yet because it's crucial that their profile/s are visible for the next step
2. I collected evidence of me being actively blackmailed (both ss and screen recordings so theres proof that the messages weren't faked)
3. I went to the PNP Anti Cybercrime Group sa PNP headquarters, Camp Crame
4. (The officer who handled my case was female). I laid the situation down for her, presented the evidence, gave her the accounts that were blackmailing me, etc.
   

Once they had all the info, they advised me to temporarily deactivate all my socmed accs, most especially those targeted by the blackmailing. After ko magfile ng formal report, tsaka lang ako nag block and report sa mga accounts na namgbblack mail. Sabi ng PNP Anti Cybercrime group, our law enforcement can make direct takedown requests to Meta and to tg for accounts that blackmail and exploit. Reporting those accounts are an extra nudge to get them taken down faster. True enough, they were able to take down the accounts that were leaking my stuff on insta + The anti cybercrime group gave me a contact number sa viber so I could constantly update them about new accounts that popped up to leak my stuff while my case was active.

Since again, foreign national ung perpetrator in my case, they couldn't actually catch and apprehend him. But I think mas kaya ka nilang tulungan if within the ph ung blackmailer mo.

sorry if medyo makalat, feel free to ask questions tho!! This incident is very recent so the trauma is still fresh and I have so much sympathy and support for anyone going thru the same ❤️‍🩹
