After reading the reviews on this site, it's clear that itwouldn't have made a single bit of difference if I had actually read every single word of the ToS before making an account on Pixabay.
I accept responsibility for not properly researching the rules and regulations, but what I will not accept is the absolutely abhorrent and unprofessional manner in which I was responded to by Simon, the so-called CEO of this company.
I have made sure to keep screenshots of the email exchanges, where he proceeded to insult me and even called me "slow" because apparently I did not understand the rules before making an account on their site.
It is also very suspicious that they keep a PayPal donation button on the page that was formally your profile when you deactivate your account. Essentially, they are making profit off of images that people donated to their site free of charge.
Do not bother with this website. There are infinitely more legitimate stock image websites out there that do not behave in this manner and will treat their users with actual respect.
