In general? I don't. If they leave a comment or review, or otherwise indicate they also have fiction on this site, I usually do check their profiles out.
I noticed that SH has some kind of "lounge" and a little list for "profile wall posts" like social media. There seems to be some very prolific SHers. Those I check out, but only because I am intrigued and it's all posted publicly.
(As another note, I tried to disable everything on my own profile, but I have no idea if I succeeded or not. It's kinda creepy, tbh, that everyone can check your activity.)
