I had the same issue when I first put up my gitea instance. The bots found the domain through cert registration in minutes, before there were any backlinks. GPTbot, ClaudeBot, PerplexityBot, and others.

I added a robots.txt with explicit UAs for known scrapers (they seem to ignore wildcards), and after a few days the traffic died down completely and I've had no problem since.

Git frontends are basically a tarpit so are uniquely vulnerable to this, but I wonder if these folks actually tried a good robots.txt? I know it's wrong that they ignore wildcards, but it does seem to solve the issue

Where does one find a good robots.txt? Are there any well maintained out there?

I will second a good robots.txt. Just checked my metrics and < 100 requests total to my git instance in the last 48 hours. Completely public, most repos are behind a login but there are a couple that are public and linked.

I suspect that some of these folks are not interested in a proper solution. Being able to vaguely claim that the AI boogeyman is oppressing us has turned into quite the pastime.
