"Donate to me" sounds like a pretty explicit appeal to give money, so I would personally steer away from that to not get in trouble with the law ("rahankeräyksellä [tarkoitetaan] toimintaa, jossa yleisöön vetoamalla kerätään vastikkeetta rahaa" & "yleisöön vetoamisella [tarkoitetaan] suullisesti, kirjallisesti tai muulla tavoin ilmaistua pyyntöä tai kehotusta antaa rahaa keräykseen").
AFAIK, just adding your PayPal details or bank account number to your website would be okay because you would not be making any sort of an appeal.
