According to the above site, 粵語協會 (Cantonese Association) uses liu1 (tone 1) for 撩鼻屎 and 撩牙. Now the score from major sources is 2:2. Any comments from other members?
粵語協會 is a well-known organization on Canto language based at Guangzhou. I find its list of Canto characters very useful as reference materials for our CantoDict project.
