Understand that the classifieds section is here on a "use at your own risk" basis. LS1Tech assumes no responsibility for these transactions or arrangements made between members. Classified sections are provided for free for contributing members.
Having said that, moderation will not prevent these possible scams. We already prohibit new users from replying to classified section threads. There is no current, past or future staff which would have time to extensively vet each account prior to registration. Users must take personal responsibility for those with whom they do business. If a member has just signed up and is using the PM system to avoid classifieds section restrictions, then it is probably best for you to ignore/delete them and report this in the Negative Trader Feedback section.
FWIW, this and two other accounts have since been banned.
