I can vouch for Glass rarely being in Blockland.
I'd like to see some higher res snaps of those chat logs. Its possible Glass is lying but there is a very real and likely possibility someone is just trying to upset him in an ironic topic. I usually wouldn't find such a thing plausible but wow, some of the stuff people say / do to Glass is just as handicapped as his original drama.
I think we all have to at least consider the option it could not be Glass from the forums at all, but not sure if it is or not, I don't have ALL of Glass' IDs on hand exactly.
I don't know why higher res pictures would help, but when I have time tommorow, I can try to get you some if you would like. Though I'm not intentionally trying to make him mad/making a drama to make a drama. I just kinda wanted to post this to show literally, whoever this is, Glass from here or not, acts like a handicap, along with his bud.
