Bloxlink for Telegram?
Short answer: it does not exist. Bloxlink and RoVer are Discord bots, and neither has a Telegram version. This explains what that means if your community lives on Telegram, and what the alternatives actually are.
Why Discord bots cannot work on Telegram
A verification bot does two jobs: it proves someone owns a Roblox account, and it acts on that inside the chat platform. The first half is portable. The second is not.
Bloxlink assigns Discord roles and renames members. Telegram has neither roles nor nicknames, so there is nothing to port. A Telegram bot has to reach for different tools entirely: muting, join requests, and removal.
Three ways to verify a Roblox account
Worth understanding, because the method decides how much you are trusting.
The profile code
The bot gives you a code, you paste it into your Roblox profile description, the bot reads it back, you remove it. It works, and it is slow. It also teaches players that pasting unfamiliar strings into their profile is normal, which is the exact habit account stealers rely on.
The verification game
You join a Roblox place the bot owns, and it reads your user id from the server. Fast, but it needs a maintained game, and it only proves you were in that server โ a shared account passes just as easily.
OAuth 2.0
You sign in on Roblox's own page and approve two permissions. Roblox tells the bot who you are directly. No code, no game, and no password ever reaches the bot. This is what Roblox built for the purpose, and it is what Studcheck uses.
Where each bot stands
Bloxlink is the Discord standard, used by millions of servers, and was acquired by Roblox. Discord only.
RoVer is open source and self-hostable, but is widely described as no longer maintained. Discord only.
Studcheck does the equivalent job on Telegram, using Roblox's OAuth login. Free, and it works in channels as well as groups.
What changes on Telegram
No roles, so a verified member is not marked visually. You check with a command instead: reply to any message with /whois and you get their Roblox account.
No nicknames, so nobody can be renamed to their Roblox username. Telegram simply has no equivalent, and no bot can add one.
But Telegram gives you something Discord does not: join requests. A private group can hold every new member at the door until they verify, rather than letting them in and hoping.
The part that matters most
A Telegram ban is a ban on a Telegram account, and Telegram accounts are free. Someone banned this morning is back this afternoon under a new one.
Once accounts are verified, a ban can attach to the Roblox account instead. A new Telegram account escapes nothing, because the Roblox account behind it is the same one you banned. That is the real reason to verify, and it applies whichever platform you are on.
Trying it
Add @Studcheck_Bot to a group you created, make it an administrator with Ban Users enabled, and send /diagnose. The bot reports exactly what it can and cannot do, which is usually where setup goes wrong.
Studcheck is independent, and not affiliated with Roblox Corporation, Telegram, Bloxlink or RoVer.
