After dealing with 20-30 spam posts a day, the search was on for something different. The positive of allowing posts is the ability to have a mini-community discussion. When dealing with 20-30 bad/spam posts a day then takes away from the functionality. These are some of the solutions that I have looked into.
Pros - A number of the spam is dealt with by Twitter, clean look with Twitter feel
Cons - A little consuming to get working on Mura, commenters have to have a Twitter account, have to stay up-to-date on twitter (constantly connected)
Pros - Pretty easy to implement, looks good, nice format with pic person and text, shows real people
Cons - having to stay connected to Facebook, commenters have to have Facebook account
Pros - Some are easy to install, some have good functionality
Cons - Some are difficult to install, still nothing is spam proof
So, nothing is perfect and I am still looking for the best solution.
Though I do like spending a little time and figuring out where the spammers are and redirecting them away from my site all together :)
So those that care, leave me a comment on what has worked the best for you. Spammers, I ask that you go away, but I know you won't, so thanks for spending your life on my site!
