I feel bad for the guys at MyBlogLog. Ever since being acquired by Yahoo, they’ve not exactly had a comfy ride. Things escalated this weekend, with reports that spammers had found an exploit that allowed them to add themselves as “co-authors” on as many communities as they wished.

To their credit, they’ve reacted well and today announced new steps to improve the community and hopefully reduce the amount of spam
