Well, the post in question has since been removed, not so much because of the issue you refer to but because it was off-topic in that particular forum.
As for backlinks generally, I think it will become evident soon enough whether a member is here to participate in discussion or to sell their wares, and we'll address each on a case-by-case basis... hopefully with the assistance of the Dhamma Wheel community who are welcome to report any posts which they find serve no purpose other than to sell or promote some commercial or illegal product.
Thanks for your interest.
"Having understood name-and-form, which is a product of prolificity,
And which is the root of all malady within and without,
He is released from bondage to the root of all maladies,
That Such-like-one is truly known as 'the one who has understood'." (Snp 3.6)
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
