Rav Shlomo Zalman Auerbach on (Certain) Sheitels
Halichos Shlomo 20:(12)
"A wig, although they allowed going out wearing one, nevertheless regarding a significant portion of the wigs available today, which are exceptional in their appearance and their salience, there is no Hetter to wear them, because they are in complete opposition to the spirit of Tznius. And the rule is that it is not the manner of Tznius that the appearance be similar to that of a Penuyah, rather it must be easily [emphasis in the original] recognizable that it is not natural hair."

I think it is likely that they're talking to those referenced many places on the J-Blogs in the past month or so.
It bears reiterating the primary point of the Seridei Eish linked to above:
"...it is the way of kosher Jewish daughters that they are nauseated by strange men placing a covetous eye upon them."
Meaning, if a woman 'appreciating the attention', she is not in tune with the inner world of kosher Jewish daughters.
