Creating multiple usernames, maybe? Maybe have one username for each thread/topic. Honestly, this is just a forum. No business is conducted here. Its on the market where most of the security should be implemented. Just do as mseller recommends. Don't say too much and be general/vague. Don't give out locations, Dates, times, names, shipping methods, bitcoin transaction numbers, DCN's etc. nothing to give out your identity or identity of other members. Only post relevant things. I think if you follow those rules, you should be ok...
