People pick Modero for the look: every message the bot sends can carry custom emoji, so your chat stops reading like a notice board. Feature-wise it's a solid moderator without frills. The description says little about the actual protection, so you'll be testing that on your own group.
Most moderation bots post the same grey service lines along the lines of user X has been warned. Modero lets you rewrite any of those messages and drop custom emoji into them, animated ones included. Small thing, but in a chat with personality it shows.
Everything is set up inside Telegram by talking to the bot, with no dashboard on a separate site. Beyond protection there's reputation: members build it up, and it shows who the community trusts. How it's awarded is something to look up in the settings.
One handy bit for forums: the bot can publish not just to a chat or channel but into a specific forum topic. If your group is split into themed threads, announcements end up in the right one instead of the main feed.
Which protection tools are inside, whether captcha, filters or flood control, the description doesn't list. Paid features aren't mentioned either. The interface is English but the menus are simple.
