I'm mainly a Stack Overflower, but sometimes stray to darker sides of Stack Exchange. I get the customary 100 rep bump since I'm a 'trusted member'. However, on a recent site I visited (English Language & Usage), I couldn't post an answer to a protected question because I didn't have 10 rep points on that specific site. So what was the purpose in giving me the 100 rep bump? More of a curiosity than anything and wondering if that's intentional or an oversight.
