Help me Ban an instagram & facebook account

[lonewolf34]

Long story short I recently caught my now ex-fiance was using Instagram & Facebook to talk & meet up/sleep with guys behind my back while I was at work. I know it's a pit petty but I know she’ll lose it, if she lost her precious social media accounts & would put a smile on my face.

Can you guys recommend a working mass reporter tool. The ones I've tried don't seem to work or know of someone who provides this service. Thanks
