I don't mind you posting pictures of your students. Lahat naman tayo dito, mahilig, at labis kong pinasasalamatan ang pamimigay mo ng biyaya.
I'm actually worried about you because your posts have been careless. It's actually easy to trace you. You have posted pictures of your students, the subjects you're teaching, and a of a girl in uniform, making it easy for people to pinpoint the school.
Even if the photos you have shared do not expose the subjects in situations that will compromise their being, the mere fact that you're a teacher sharing your students' pictures can be strongly construed as an act inimical to the moral ascendancy you have over them.
What does this mean?
If your school catches wind of your internet activities, it would be enough ground to terminate your employment.
If the students or their guardians catch wind of your internet activities, it would be a solid case for damages based on the aforementioned relationship imbued with moral ascendancy.
I am not asking you to stop posting, my friend.
I'm not even asking you to "respect" your students... as I, myself, have slowly undressed them in my mind... thank you very much.
I'm just asking you to do a better job in hiding your footprints.
