Paid rhannu dy gyfrinair gyda ffrindiau. Cer i weld y cyngor yma gan Internet Matters<\/a> am osod cyfrineiriau ac enwau defnyddwyr.<\/p>\n\n\n\n

Mae Meic wedi cael sawl person ifanc yn cysylltu sydd wedi dioddef o flacmel ar \u00f4l gyrru lluniau noeth i rywun maent wedi cyfarfod trwy chwarae gemau ar-lein neu ar gyfryngau cymdeithasol. Efallai eu bod wedi credu bod y person roeddent yn siarad \u00e2 nhw o gwmpas yr un oedran. Ar \u00f4l gyrru’r lluniau, maent wedi cael wltimatwm bod rhaid gyrru arian neu mwy o luniau noeth, neu byddant yn rhannu’r lluniau.

Os wyt ti’n poeni am unrhyw beth sydd wedi digwydd ar-lein, yna dweud wrth rywun. Hyd yn oed os wyt ti wedi gwneud rhywbeth nad oeddet ti i fod ac yn ofni cael row, mae’n llawer gwell dweud wrth rywun na phoeni neu drio datrys pethau dy hun. Os nad wyt ti’n teimlo fel y gallet ti ddweud wrth y bobl agosaf atat, yna gallet ti geisio siarad ag oedolyn gallet ti ymddiried ynddynt (fel athro), neu gallet ti ffonio ni’n gyfrinachol ar linell gymorth Meic.
