Friends are helpful, whether online or in person. In this case, it's online, and that's where things get a little bit iffy. We are all scared of identity theft, stalking, and so on so forth, but don't let that stop you from making some friends on this platform! As long as you stay safe, and watch what you message the opposition, you shouldn't have any issues.

The first order of business is to be nice to all others. Even if you are trying to stay in character by being a muggle-born hating death eater, just don't take it too far. Remember to never say anything openly offensive to someone's race, body weight, or anything severely mean in general. This can be very offensive to people and hurt them more that the sender could imagine.

Open up to all houses of people! Having a diverse community of friends with different opinions to wizarding world issues never hurt, in fact it helps more. We can share opinions, and even memes if needed with each other. That makes for an ideal online friendship.

Also, read their bio before opening up. You can role-play when talking to different people such as if you were communicating to a death eater, as opposed to a professor at Hogwarts. You would definitely speak to them both in completely different ways.

These tips may be cliche, but they really do help! If you want to establish a long-lasting friendship with many Hogwarts students, ghosts, or even dark lords, then go ahead and use these as a base guideline!
