You may have heard of SquidHQ, and it’s bypassing of the blacklist, but might not have started using it because “we don’t need to, PCB is EULA-compliant”. However, I would like to encourage others to start using it, right now, because Mojang has started blacklisting servers without notification. While PCB may be compliant to the EULA, we must encourage players to pick up the incentive - If players use SquidHQ, it tells Mojang that the players do not agree with their forcing of the EULA on the players. Many servers have been blacklisted just for minor offences to the EULA.
Not convinced? Here is a snippet of a server’s owner’s stance on the situation.
Server owners should be pushing for SquidHQ as much as possible and applying proper incentives now. If they wait until they're blacklisted to push it, players will be cut off from the main source of information.
If you intend on being compliant, you should still push for players to use SquidHQ as soon as possible. Just as Mojang expanded their EULA to block vote rewards, they may once again expand it in the future to block cosmetic rewards. They may decide to blacklist without first contacting server owners. You do not want to find yourself stuck in that position. Take the proper preventive measures - Push for SquidHQ regardless of how you intend to go about handling the EULA.
General piece of advice to server owners who didn’t figure this out already.
SquidHQ is exactly like the regular Minecraft launcher, except it bypasses the server blacklist. All your regular saves, texture packs, and mods will work on SquidHQ as well as they do on Vanilla. You do not need to login again on SquidHQ if you have logged in on Vanilla, and if your anti-virus detects something, be ensured that it is safe. If you are not convinced, SquidHQ is a open source project - you can go in and read the source code if you’d like.
Please do use SquidHQ - it works on PCB, too.
