A word of WARNING.
There seems to be some very strange looking profiles adding lots of triathletes on Facebook. They appear to be targeting members of 'The Ironman Journey' group specifically. Friend requests were sent out to thousands of people, and they were posting updates announcing they required triathlete ambassadors for a new sports brand (no details of brand or product provided).
The profiles are newly created and have no previous Facebook history (created in the past few days). They seem to post exactly the same updates, list similar places of work (Rising High Triathlon) and share similar profile and timeline photos. Sonja Wieck at Rising High Triathlon confirmed they are not associated with her company.
All very suspicious.
Some of the profiles.
