I have not spent my time to investigate the case of perm-banned OP, because I don't have too much time and enough skills to do this.
However, publishing snapshotted images without permissions from owners of those photos, or sites won't lead to plagiarism, at least in the forum.
Admin raised his opinion in another topic there.
- That's not plagiarism.
- If there is dox outside of the investigations section, report it with that as the reason.
- If someone is threatening violence against you, report it with that as the reason.
- If you have a copyright claim, you have to PM/email me a valid DCMA takedown notice with all required elements, including your address, a declaration under penalty of perjury, etc. Note that I will forward your notice to the affected users.
- The forum is not under EU jurisdiction.
It is obviously that members should leave source link to sites or places where you get those images for their posts or topics, but without links, they won't be judged as plagiarism in the forum, so far.
I could be wrong, but mostly perm-bans come from plagiarism, so the OP case probably due to plagiarism (content plagiarism, not photo plagiarism).
