Fake LinkedIn profiles
It has come to our attention that more and more random people worldwide are posting profiles on LinkedIn where they claim to be employed by our company, including using bootleg copies of our company logo. Please note we are a small company with only 1 office in California. We employ nobody outside California nor employ any vessel crew. Anybody implying otherwise is lying and should be reported to LinkedIn as such. Thank you.
