Unfortunately the Twitch support doesn’t care about the User Voice Forum, see also the date of the post, which has been there for some time.
I find it hard ridiculous, from twitch.tv that there is a 2k channelfollow limit for other channels, I thought Twitch wants to be better than Youtube, there is no follow channel limit for the viewer.
This forum is for third party developer support, we cannot help with the issue you have described as it’s a first party issue, and you have already made a suggestion for the issue you have described on the uservoice.
