Seminaries (similarly yeshivas) are often in a bind — they want to hire the “charismatic”, “enthusiastic” kind of mechanchim that will “inspire” their talmidim, form close bonds with them, invest tremendous time in talking with them about their problems, etc, but it is particularly those types of people that we more often find crossing boundaries. Dry teachers, who might even be seen a bit as aloof or out of touch, and who focus primarily on teaching (and less on “connecting”) might not draw in new students, even if they do end up being the teachers that are the most substantive and offer the most to students. Ask any person running a seminary, and they think about this issue all the time. Halvai all yeshivas/seminaries would focus on hiring teachers who focus on *teaching*, and less on connecting (and possibly hire as very separate roles someone like a mashgiach or mashpiah), and I think students would be much better off — they would learn more and be manipulated/abused less.
Anyone familiar with the world of chinuch will of course realize similar dilemmas. And the focus of many kirruv organizations is primarily, if not exclusively, to connect, with teaching being a mere excuse through which to connect.
