WhatsApp and Telegram links under ads: the control built for them

A WhatsApp group invite, a WhatsApp channel link or a Telegram address under your ad is recruitment: the channel sells betting scores, signals, coupons or jobs, and the comment is its only advert. As of September 17, 2026, it is the largest link genre under my Facebook ads, 90 comments since July 1, and Facebook has a control built for it, Moderation Assist's Links to specific sites, where two domains are typed once.

Below: what the comments look like with dates and counts, what is behind the link, Facebook's domain control and its link criterion, Instagram's entries, the copyable rule, the one exception for a business that runs on WhatsApp, and why delete rather than hide.

What they look like, and how many

My three Facebook Pages received 90 comments carrying one of these addresses between July 1 and September 17, 2026, from 33 accounts with an id: 44 WhatsApp group invites (chat.whatsapp.com), 25 Telegram addresses (t.me), 19 WhatsApp channel links. 84 of the 90 sat under ads. 88 were removed, 39 by the link rule as they landed and 43 by a cleanup of older posts; the remaining two arrived under a Page whose rule ran later.

The shapes, as written and with their days: a bare group invite with tracking parameters and nothing else (September 9, 10, 13, 14, 15, one of them twice from the same account); a channel link with one word of bait, "T'as vu ?🤩" (September 11); a group invite under five pointing fingers and "Coupon du jour disponibles" (September 12); a Telegram bot with a referral parameter (September 16); "Rejoindre le nouveau groupe maintenant pour bénéficier des scores exact" with a group invite (September 16); an Arabic promise of fifteen dollars per person invited through your link, with a Telegram address (September 9); an Urdu channel for daily investment apps (September 15).

What is behind the link

The comment text says what the channel sells, and each is a line in Meta's Prohibited Commercial Practices policy, read September 17, 2026. Betting scores and "sure tickets": the investment lines on returns "guaranteed or risk-free". Trading signals: the same, and the crypto-signals field guide has that genre alone. Referral bonuses for inviting others: compensation "based on recruitment of others to participate in the scheme". Coupons "du jour": the deceptive-URL lines of the spam standard. Nothing on the other side of these links is for your customers, which is why the answer is the domain and not the words.

Facebook: block the domain

The criteria dialog on my own profile (September 8, 2026) offers two rows for this. Link in comment hides any comment "that has a link", the blunt one. Links to specific sites is the precise one, and its screen reads: "Admin Assist will stop all links from any domains you add", its example being that a bare domain stops every address under it, and "You can also add specific site URLs." Type the WhatsApp domain and the Telegram domain, and every group, channel and bot address above is covered, with your customers' links to anything else untouched. The limit, in Facebook's words: it "only hides comments made after you create the criteria", so the backlog is yours. Comments with links has the two criteria side by side with the domain table.

Instagram: three entries

Instagram has no domain criterion, as of September 17, 2026. on Instagram's Hidden Words page, read September 5, 2026, the custom list takes words, phrases, numbers and emojis, and comments that contain any are hidden from everyone but their writer without telling the writer, so the entries are the pieces every such address contains: "t.me", "chat.whatsapp", "whatsapp.com/channel". A comment cannot lose them and still link anywhere. Report the account as well, from the held comment; Instagram Hidden Words, tested has the screen.

The link rule and the whitelist

CommentWatchDog is an AI comment moderation tool that automatically hides and deletes spam and damaging comments on Facebook and Instagram ads and posts. Its URLs rule reads every comment on every post and ad of the Page as it lands, and on my Pages it is set to Delete, which took 39 of the 90 above before anyone read them; its whitelist keeps the domains you name. The whitelist and what to allow is the guide.

The one exception: your own WhatsApp link

A business that sells on WhatsApp posts its own wa.me number under its ads and wants customers to share it. A rule that removes every link removes those too, and Facebook's Links to specific sites is the wrong tool there, since it blocks by domain and the good and bad links share one. The answer is an allow list with your own domain and number on it, and a hidden view read daily for the customer who pasted a friend's link; the count above says how rarely that happens, since none of the 90 was a customer.

Why a channel link is deleted, not hidden

Facebook's hide page keeps a hidden comment visible to the writer and the writer's friends, and an address has no reader worth that: the writer is a channel operator who will not look at your Page again, and the two people who might tap it are the ones you are protecting. Delete, and report the account from the comment's Options.
