Also, the "bot" would have to bypass the google recaptcha, and the fact that it would be able to accomplish that is highly unlikely.

Also, the "bot" would have to maybe use a proxy (?) in order to bypass the IP restriction to one user per hour per claim.

Also, if the "bot" would have to be used in the "multiply btc" section, there is no guarantee on the gain as there is no guarantee on the gambing in general.

So, if the user proposing these aspects is ignoring them we can conclude that (a) he's stupid or (b) it's safe to assume the bot is trivially a scam whereas you're sold a tool that would simply not work - same as receiving a package with a brick inside.

Worst, the bot could also potentially be a worm/trojan/virus and send your login and password to the user selling it who would simply steal all your freebitco.in balance.

tl;dr; don't fall for this shit.
