Pinterest complaint: removal of pins

I keep getting notices that they have removed my pins. They provide a one time link that either links to a blurry image or to the main search page. IF they are REALLY interested in getting people to review their pins and not post things that are against their ‘guidelines’ then wouldn’t it behoove them to SHOW you the pin that is wrong? Since I cannot SEE the offending pic, how am I going to avoid doing something similar in the future. My Pinterest pages are TOTALLY devoted to interesting art or photos for reference for future paintings done by me. They ALL exclusively found on Pinterest (outside of my original art, and THOISE I guarantee are NOT pornographic!) . But I am happy to comply with their standards if I would be able to know what they were. I DO NOT pin, collect or post pornography. Is ther any way to do something about this? Its annoying!
