[Savannah-help-public] Savannah tracker spammers

[Adam Fedor]

FYI, I've started to get spam on some of my project trackers (bugs, for 
instance). See for example:

https://savannah.gnu.org/bugs/?func=detailitem&item_id=5871

I've had to require users to be registered/logged in to make 
submissions or comments. I wonder if there is any other way to stop 
this?
