The organiser of a Back-a-Buddy page raising funds to buy a new coffee machine for Warrant Officer Karl Sander has issued an alert about mirror campaigns.

Speaking to IOL, who first reported on the campaign, Kyle van Reenen said he has become aware of similar campaigns that have since emerged following the success of the page he launched.

"I have also become aware of what appear to be mirror campaigns that may have emerged following the success of this initiative. While I cannot comment on their legitimacy, I will be engaging with BackaBuddy to bring them to their attention so that any necessary verification can be undertaken," he said.

"For those wishing to support this cause, I encourage you to ensure that any contribution is made through the original verified campaign," van Reenen added.

So far, R207,889 has been raised for a new coffee machine for Sander.
