Stopping people from contacting you randomly on WhatsApp… Is that a thing?

Hi there!
Actually, it isn't possible to do that. The only way to prevent people from contacting is by either blocking them al or blocking them from being able to add you to groups.

I don't think that you're socially retard.
I spend a lot of time chatting on Discord servers, and some of my closest friends only contact me when they need help with software or other issues. It hurts me, but they don't seem to understand.
I used to enjoy socializing in person, but my circumstances have led me to develop mostly online friendships ahahaha.

In iphone its horrible, voice over focus jumps all time and makes it hard to use the app.
I use it in my windows pc and it works fine

That's probably the best way, remove and delete the chats.

Good morning. Primarily, I use LINE and ‎WhatsApp for my chat app choices. Getting added to a group can happen even if you do not socialize heavily and joining lots of groups. I use these apps for my gaming life to communicate with my people outside of the battlefield, which is extremely important in my given scenario. Anyway, I find that, sometimes, I am added to strange groups or individual chats, despite also trying to tweak these settings. I don't fuss with it, I simply go in and block the individual, or leave the group and delete it, depending on the need. But, I do use both of these apps very heavily, and find them, though they have a little bit of quirk here or there, very dependable apps, and I'm very thankful for them. They have become quite a necessity for me.

I don't talk to them and just move on. If you say hi, they won't leave you alone.
