This question is an exact duplicate of:
I've recently started exploring some of the newer sites within the network, and notice that I haven't received the usual 100pt "association bonus" on all those that I have joined (Sustainability and Travel being two cases in point - I'd link to my profiles, but I'm using the mobile app and can't easily obtain links).
I'm not in the slightest bit bothered - am merely curious: what are the criteria for earning an association bonus?
Okay, that's strange. The problem appears to be in the Android app—last night a different bunch of sites were shown with only 1 rep, but right now it's just [ux.se] (why isn't that markup shortcut working btw?):
