Meta is going to extensive lengths to prevent users in Europe from accessing Threads, including attempts to use the service while using a VPN.

Meta has seen massive success for Threads, its Instagram-connected take on Twitter, with over 100 million accounts now set up on the social platform. While Meta may yearn for even more users, it’s working to make sure that they don’t come from the European Union.

“Threads is not currently available in most countries in Europe and we’ve taken additional steps to prevent people based there from accessing it at this time. Europe continues to be an incredibly important market for Meta and we hope to make Threads available here in the future,” Meta said in a statement.
