[feature suggestion] generate a database of spam comments

[elypter2]

accounts can be blocked but spammers can easily create new accounts and continue with the same spam messages as they did before. for spam messages that are not automatically detected you have to manually look for new accounts. if there was a list of unique comments then repeated offenders could easily be detected. to protect from slightly modified comments they could be trimmed off of all invisible or all non text characters and additionally have a spell checker correct intentional spelling mistakes. the script could then add an additional option to match this list of normalized unique comments.
