Does 4Chins have a problem with Linux machines built as VMs?

I have recently spun up a Debian 13 machine in Virtual Box and wanted to use it as my daily driver for the newxt few weeks. However EVERY tme I post here I get the 120 second cool down. Its not happening with a Windows machine here. Nor is it happening with my phone which is on the same network?
Is there something in place here that regards Linux VMs as always suspect and thus treats them in this way?
Its a pain in the ass.
