sure, showing up on suggested friends is weird. the way linkedin does it makes more sense: "these people have viewed your profile". i was picking up on hiding it outright. while that may be justified in your case, it's also reasonable to let them know.

the only people i would really not want to find out that i look at their profile are spammers and scammers (oh, and stalkers).

so both sides have a fair reason. so guess, if you can, choose the social network that works the way you prefer.
