I want to warn the moderators that the level of spam is alarmingly on the rise. Two days back, I saw two spam threads opened in the 'Business of Photography' forum. Today, there are 11. Its getting flooded. Why are these fake users allowed to post in forums without verifying their accounts? I am worried, these people (or bots) may be testing the water, and we may have a bigger attack soon that can take the site down. Can we make sure new account creation is made more secure by using advanced CAPTCHA and image based tests, plus limits are placed on how many threads one person can open in a particular forum at the same time? Also, some forum sites place additional safeguards on new members. For example, threads posted by new members have to be approved by a moderator before being displayed in the public forum. This can be done for a limited period for each new member before that person is trusted to post stuff without vetting.
