Instagram says it has fixed a "bug" that saw users geo-tag themselves as being in Singapore in a bid to go viral - even though they were not there, BBC reports.

Some users claimed the apparent hack increased the chances of a post reaching the coveted Explore page on the photo-sharing app.

Posts in that section are likely to get many more likes and attract followers.

Instagram confirmed to the BBC that it was a "bug that impacted engagement" when posts were tagged with Singapore.

Like on Facebook, what appears on your Instagram is based on the firm's algorithm. The spokesperson added that they have now fixed the issue.
