Most low-quality Telegram groups can be detected in 60 seconds by checking nine concrete signals. This checklist is what LetsTG editors use internally before accepting a group submission.
TL;DR — Skip groups that fail any two of these nine signals: clear description, working admin contact, recent activity (24-48h), real member-to-message ratio, no scammy promises, no @-pinging spam in pinned posts, working external links, plausible name (no random suffixes), and category match.
Read the first 200 characters of the description. Quality groups state the topic, the rules, and a contact. Low-quality groups list buzzwords and promises ("biggest", "exclusive", "100% profit").
Look for an explicit @username for an admin. Groups without an admin contact are unmoderated and rule violations cannot be reported.
Open the chat and check the last message timestamp. Niche groups should have activity within 48 hours; mass topics within a few hours. Dead groups never come back.
A 50,000-member group with 5 messages a day is bot-inflated. Healthy ratios are roughly 1 active message per 100-500 members per day depending on niche.
Any group promising "100%", "guaranteed", "secret", or "leaked" is the universal red flag pattern. Real expert groups under-promise.
Pinned posts should contain group rules and admin contact, not advertisements. If pinned content is pure promo, the group is a marketing channel disguised as a community.
Click 2-3 external links from recent posts. Dead links across multiple posts indicate no editorial maintenance — the group is on autopilot or abandoned.
Real communities have human-readable names. Groups with random suffixes (Crypto_Group_2024xZ91) are usually generated in bulk by spam farms.
Compare the description with what the group actually posts. A "Tech News" group that posts mostly job ads has drifted — it will not deliver what its name promises.
Two failures = skip. Three failures = report to LetsTG via the in-listing report link so other users do not waste time.
Two failures = skip. Three or more failures = report to LetsTG via the in-listing report link so other users do not waste time.
Roughly 1 active message per 100-500 members per day, depending on the niche. A 50,000-member group with only 5 messages per day is almost certainly bot-inflated.
"100%", "guaranteed", "secret", "leaked", and any promise of risk-free profit. Real expert communities under-promise.
Group rules and admin contact. If pinned content is purely promotional, the group is a marketing channel disguised as a community.
