I have a friend who has a internet SO who seems to be potentially a scam. He periodically gives her/him gifts, she/he was afraid to talk to any of his/her freinds for years, she/he dissapears randomly, her/his voice seems to be modulated and we belive my friend gives more gifts than she is leading on as her/his paycheques dissapear. When the SO says longer sentences it becomes glitchy and feed backy. I know it could be the SO has bad interner or a poop Mic but is there anyway to look for undertones of modulation so we have some proof or anything? Before potentially breaking his heart, as I dont want to but worry for him/her?..
