Nostalgia wears off and channels like Challenge just end up on an infinite loop, so even if you're the biggest Bullseye fan in the world soon enough you've seen everything there is to see. Frankly for most of us even with our favourite shows we often just want a taste of nostalgia rather than to have the full course night after night.
The other bigger problem for Challenge is the genre itself. In the late 90s and through the early noughties there was alot of fairly recent content from the 80s and 90s to build a channel around, but now there isn't a huge amount of stuff from the last couple of decades to add to the schedule - and the biggest hits of The Chase and Pointless already dominate the schedules, along with Millionaire. They've tried other content like Deal or No Deal which would have filled hours but that's just not worked for them.
All that said though I wouldn't read too much into their lack of social media effort - I suspect the actual audience of Challenge and their followers on Twitter etc. don't actually overlap that much.

I preferred the internet when it had a sense of humour.
