The issue here is not merely paying someone for the service; the problem, from my experience, is that anyone taking money for this service insists on articles they claim are necessary. This forms a significant scam that many people fall victim to. Then comes the verification process, which is uncertain for both parties; success depends on luck. If it doesn't work, the seller has already earned 5k or 9k from articles costing less than 1k. Unfortunately, articles' money can't be refunded as they're already posted, but verification money, which is often refunded, can be reclaimed (sometimes).
I personally have attempted to verify my own Facebook profile and Instagram, encountering numerous individuals offering such services. They typically request articles, even though I have more than 30 fully featured articles, a ready knowledge panel, and a strong presence on Google when my name is searched. Despite this, they insist it's not sufficient and demand 5000 for articles and an additional 5000 for verification, totaling 10k. Some even ask for 23k. All of this proves to be a waste of time and money.
Through my experiences, I've learned that investing in ads is a more worthwhile approach; eventually, you can attain the blue tick. Otherwise, attempting verification through other means can lead to wasting both time and effort.
