Ева bot review: Does this contact cleaner actually work?

What Ева bot does (and why I needed it)

I manage several Telegram groups where engagement slowly declines over time. People change phones, abandon accounts, or simply stop opening the app. Dead members skew analytics and make groups feel inactive. Manual checking is tedious - that's where Ева caught my attention.

This bot scans your group or channel to identify inactive members based on last seen status. It doesn't just show data - you can mass-remove ghosts with approval. The interface is entirely in Russian, but even with basic language skills I managed to navigate it.

Key functions I tested:
🔹 Scanning groups up to 10,000 members
🔹 Custom inactivity thresholds (30/60/90+ days)
🔹 Whitelist to protect important members
🔹 CSV export for manual review

Unlike some admin tools, Ева doesn't require bot admin rights initially. It works as a regular member until you grant specific permissions for cleaning.

Hands-on testing: Cleaning a 1,200-member group

I ran Ева through three scenarios to evaluate real-world performance:

Test 1: Quick diagnostic
Without any admin rights, the bot analyzed my group in 4 minutes. Found 87 accounts inactive for 90+ days - matching my manual spot checks. The report showed:
📊 Last activity distribution
📈 Percentage of inactive users
⚠️ Suspicious accounts (likely deleted)

Test 2: Deep clean with removal
After granting restricted admin rights (no message deletion), Ева processed removals in batches. Took 15 minutes for 87 accounts with confirmation prompts between batches. Zero false positives - all removed users were truly inactive.

Test 3: Whitelist protection
Added 10 VIP members to whitelist. The bot correctly skipped them during scanning while flagging adjacent inactive accounts. This prevented accidental removal of valuable but quiet members.

The only hiccup occurred when scanning a group with slow-mode enabled - had to temporarily disable restrictions for accurate results.

Who should (and shouldn't) use this bot

After two weeks of testing, I see three ideal use cases:

1️⃣ Community managers - Keeping groups engaged by removing abandoned accounts that inflate member count
2️⃣ Channel owners - Cleaning subscriber lists before running promotions to improve reach metrics
3️⃣ Small businesses - Maintaining clean customer chat groups when Telegram is used for support

However, I'd hesitate to recommend Ева for:
✖️ Very small groups (<100 members) - Manual checking is faster
✖️ Sensitive communities - The 90-day threshold might remove temporarily inactive but valued members
✖️ Non-Russian speakers - While menus are simple, all notifications and buttons are in Russian

The bot works best when you combine its automation with human judgment. I always review the CSV export before mass removal, especially in professional communities where people might be legitimately busy for months.
