Sorry but I call this BS phishing attempt, mainly because why would any serious AI researchers first turn to a miner forum - regular people, instead of going to some high class universities/ some other institutes...etc. anywhere in the world and collaborate with their departments there?
I'm sure lots of universities/institutes would be open for these kinds of things and are well funded for these kind of projects if there's a good initiative...
If it's fishy, it's usually because it is...
just my 2 cents.
In the reddit post it says "I had a friend who was mining Ethereum on his Nvidia 1080 ti's. I would Venmo him double what he was making by mining Ethereum, and in return he would let me train my neural networks on his computer at significantly less than what I would have had to pay AWS."
And
"Compared to the GPU server I rented from AWS, my neural net (using TensorFlow) trained ~5x quicker on my friend's mining rig which had one 1080 ti."
Note the Nvidia K80 costs $20 usd a day and is 5x slower than a 1080ti.
To them it makes economic sense to find cheaper alternatives to AWS. BTW my university only has a handful of K20X Teslas (which has a tenth of a 1080ti Tflops) and we are considered very well off: http://www.its.hku.hk/services/research/hpc/hpc2015/configuration
Institutes resources pales in comparison to miner's hardware. Phishing is always possible, the brave ones will test first.
