Community websites with open registration are a constant target of spammers. EnviroDIY.org has extensive measures in place to deter them (we blocked over 100 spam registrations just in the last week) but it’s an arms race and spammers develop new tactics in response to these measures.
Unfortunately, on Monday morning someone registered with a clean Gmail account and quickly posted comments on multiple blog and forum posts. I blocked and deleted the account as soon as I saw the activity and reported it to our anti-spam blacklist.
I apologize for any inconvenience and will continue to look for new ways of blocking spammers. Feel free to email me at firstname.lastname@example.org with any questions or concerns.
