AHS- online

Basically it features a group of different characters living in different parts of the USA who are connected via an online forum/message board. Something like a true crime/urban legend/conspiracy theory site. Each character has a reason to visit the site as we delve into their back stories they start individual investigations into whatever their stories are, whilst being supported by anonymous strangers online. Something along the lines of different people realising they have a shared experience and try to work out what they saw.

For anyone who wass a fan of CreepyPasta think along the lines of Candlecove or 1999

The last few episodes could feature some characters coming together in real life and meeting in person.
