Why was my post about the block feature removed

Because you already have similar threads related to that topic. As mentioned in the forum guidelines duplicate posts will be removed.

Well the reason he had for blocking me was very silly. That is why it should be removed

The reason may be silly to you, but not to them. It's not up to you who another person wants to block or not. It's entirely up to them. Bypassing that by using another account can also count as harassment on your part.

I'll be locking this thread now since you've brought this up several times over the past few years.

i'm sorry, they're not going to remove the block feature in fact it's something that's required by many services

You're unlikely to find any major service without it

The block feature is extremely useful to prevent anyone harassing someone or spamming them with invites/party invites etc. so they aren't going to remove it anytime soon.

If your "friend" has blocked you then they have their reasons & it sounds to me like the block tool is doing exactly what it's meant to.
