Yes, sadly so. Some of the ones who are gullible enough to use an unregulated, high-leverage broker and be scammed the first time around are also still gullible enough to be scammed again by dangling “fund recovery” in front of them.
The legitimate ones are called licenced, registered lawyers (but will typically advise you that your recovery prospects are close to non-existent if there isn’t a proper, recognized regulator to involve, especially if the “broker” is in another country).
