Main author of x64dbg here. This is very probably the case and I contacted Github support to figure out what is going on. Before today we had around 3k (legit) stars.
I've never heard of your project but woke up this morning when my phone started buzzing with alerts from issue #1864. Looks like my account somehow has ended up starring and watching your project. That probably explains why you have replies to that issue saying "Unsubscribe" and "what?"
