That's exactly it, the CMA have closed the loophole by clearly stating that gifts and freebies are now very much considered "payment in kind" and that whether or not you were paid actual cash to share it with your followers or whether the brand has editorial control no longer determines whether you're advertising to them. Chloe Loves to Shop is talking about her interpretation of the ASA rules but she seems to be blatantly missing the point in the ASA flowchart that says gifts / freebies are not covered by ASA but CMA rules apply.
But CMA rules apply here – you must make sure content is clearly identifiable as being paid-for. For example, by using the label ‘advertisement feature’ or ‘advertisement promotion’.
How can she have that document in front of here and not see that gifts need to be marked as an AD. Not to meet the ASA guidelines but to meet the CMA guidelines.
