The link shown in the description MultiMC shows leads to https://www.curseforge.com/members/tr7zw/projects which is outdated if you try going to it.

I have no clue where MultiMC gets that data from, but technically it's the correct link. Currently the name is tr9zw on Curse because Twitch fucked up my account and support wasn't able/willing to recover it. So the link will be correct again as soon as Curse accounts are no longer connected with Twitch(they are working on it).
