WeChat is an internet-enabled communications platform that offers free video and voice calls, videos, images, games, stickers and text messages. WeChat users can also add new friends through location-based services (LBS) or Shake.
WeChat ID is your unique identification within WeChat and can only be set once (changes are not allowed). Your friends can try to add you by searching your WeChat ID.
From the "Me" tab, tap your avatar photo, then "WeChat ID". Keep in mind that once you have set your WeChat ID, you will not be able to change it, so make sure your ID isn’t too personal e.g. full name, mobile number, etc.
If you've encountered harassing, unsafe, or illegal behaviour, it's best to report it. Tap on the offender's avatar, then tap the "…" button in the upper right corner of the profile screen. From the resulting menu, choose "Report". After you submit the form, the WeChat team will investigate.
You can delete someone in your contacts:
Select the friends to be deleted on Contacts, then tap the “…” icon on the top right, and tap “Delete” to remove them.
If the person you've deleted keeps trying to contact you, you can go one step further. From their profile page, tap the "…" button in the top right and flick the switch labelled "Block".
