No worries, no offense taken.
I still can't believe myself I fell for this, as said I have 2FA on all accounts and I'm normally very cautious. I guess it's a combination of all the factors here at play: Facebook allowing a fake TikTok Ads advertiser, the ad looking very legit (referring to an existing ad credit program), Google allowing a fake TikTok Ads app with fake reviews, and not getting any notifications until the amount was charged from my PayPal account.
