How do you manage the risk of people hijacking your community❓
A community by definition has some degree on openness.
⚡ 1. People come inside and spam their stuff (we all know how this is done, you just delete it, but the community was already disrupted)
⚡ 2. Someone can infiltrate your communicate and private message and spam all your members as they are visible on most platforms.
⚡ 3. MORE ADVANCED: Someone could collect data over the long term about all of your members activity, get their contact data, names, messages etc and then later use it to spam them and push commercial offers or even political ideas. I guess this is not even complicated, actually it's quite easy.
