IbnRiad's account has been withheld in Europe due to a legal demand, as they themselves have acknowledged on X. While specific details of the legal complaint aren't publicly detailed in the information available, the context from the posts suggests that it might be related to their commentary on the Israel-Palestine conflict, which can be sensitive and politically charged. Here are some insights based on the available data:

Legal Demand: The blocking of IbnRiad's account in EU countries seems to stem from a legal action, which might be connected to accusations of hate speech, incitement, or content considered too controversial or inflammatory under European laws or regulations concerning online speech.

Freedom of Speech Issues: There's mention of this situation being a case of "failed freedom of speech" by another user, indicating that some perceive the blocking as an overreach or censorship, especially given the account's moderate wording as described.

Zionist Complaint: One post suggests that the legal complaint was filed by Zionists, indicating that the content posted by IbnRiad might have been deemed as offensive or promoting anti-Zionist views to a degree that led to legal action.

Platform Response: X (formerly Twitter) responds to legal demands by blocking or withholding content in specific regions to comply with local laws, which in this case led to IbnRiad's account being inaccessible in the EU.

Workaround: IbnRiad has advised users in Europe to use a VPN to access their main account, indicating that the content is still available outside of the EU or through methods to bypass regional blocks.

This situation reflects the complexities of international law, local regulations on freedom of speech, and the internet's global nature where content can be moderated differently across regions.
