Getting SPAM using notes

[karthik085]

Hi,

I am using Mantis Bug Tracking System and getting lot of spam - spammers are using "Add Note" feature on the issue page. So, under an issue, there are lot of spam notes left.

I looked at my server logs - each spam note is from a different IP. So, I can't even block them. Should I install a captcha solution or any other anti-spam solutions? Any other way in mantis to stop this? Any suggestions are welcome.

Thanks,
Karthik
