With the subsequent development of the internet, it transpired every year that, following complaints from other customers, not only thong swimwear but also fundoshi was prohibited at pools to which men wearing thong swimwear or excessively transparent swimwear with very little of fabric came in droves because it had been stated on the internet that it was permitted to swim there wearing thong swimwear.
その後のインターネットの発達に伴い、Tバック水着で泳げるとネット上で話題になったプールにTバック水着の男性や、布の少ない、透ける過激な水着の男性が殺到したことから、他の客から苦情が噴出し、褌まで禁止となる事態が毎年のように起きるようになった。
