I don't advice anybody to use those anonymous services started by brand new accounts. Before all, telegram is the worst place to start with, for both lunchers and users, especially with those confirmed bot use.
The service has no known reputation so it's not trustworthy until proving the opposite.
Can directly vouch for this - It's in a lot of crypto community group in which it's being actively used. Bot checker, deletes links, images, forwarded messages which is a timesaver - allowing anyone moderating a group to just do what they're supposed to do, network with the people instead of going to bed and waking up to 500 spam messages!
Secondly strongly suggest you do your own DD before you criticize someones project like that. Go into the groups where the bot is operating, or even look at the site itself to see which project it is involved in. There are some big names on it. It LITERALLY proves the opposite.
The bot under no way adds users, but moderates the group/channel/chat; as I mentioned above
