Still not sure how I was supposed to get "RobertDalePendleton" as the decode for that, but it leads to GrandpasVCR.com - it's definitely positioning itself as a Ready Player One ARG, although the connections to the one already running are somewhat strained, with a number of signs pointing to fan game, just to help manage expectations. Underlined letters are JVS, which points to VHS tapes, as does the diagram which is apparently of VCR innards.
