Would 911 consider it an emergency if some stranger keeps texting you
not unless that stranger is physically endangering you. if you're bothered by a stranger, call the police, not 911. the police can help you out a little.
It depends what they are saying
No 911 in only in life or death situations so unless that person is putting you in danger than no. But you can call a non emergency number or just block his/her number.
No. Unless that person is making threats of harm towards you. Then you should talk to the police.
No. Don't waste their time.
If they text more than 5 times tell authority
no..but depends what they are saying..if they are really weard and writing funny stuff then maybe..but someone got my number and kept texting me but that number that person had before so i told them they had the wrong person and they stoped.
If you are not immediate danger it's a crime to call 911. Call the police through their normal telephone number. It's probably just someone with a wrong number.
