These comments are not appropriate. The guidelines and the FAQ both state that calling out users is not acceptable.
Comments such as this can result in suspensions, so I advise you to refrain from this behaviour in the future.

Guidelines:

If you have an issue with another user, submit a ticket with a user report, rather than calling them out within the community or on the forum.

FAQ:

I think I spotted a fake giveaway, what should I do?

We typically allow all giveaways to run their course without judgement, and allow the giveaway creator a fair chance to prove themselves and to come through with the gift in the end. An exception is when the giveaway creator enters a description that clearly states the giveaway is fake, or if the description illustrates a lack of understanding of how the giveaway system works. Please refrain from posting any comments accusing the giveaway creator of posting a fake giveaway, and only create a support ticket if the giveaway is fake beyond a reasonable doubt.
