We use telegram:

1) As a measure to protect against bots and threat actors.
2) As a service to send you notification for your uploads & withdrawals.

For transparency reasons, we'll guide you through the steps on how telegram login mechanism works:

1) You perform /start command on our telegram bot
2) It gives you the link with authentication token, which will log you in upon following.

The process is 100% safe as you're essentially just using the bot and not actually linking your telegram anywhere.

What should I do?

You are probably trying to send us a unsorted file, hence its size is too big. Use our open-source sorter (or any other with live.com query) to shrink the file size dramatically.
