We have encountered more and more issues with new users lately, and there are several recurring issues.
1) Do not post phone number and email in your ad. Unless you want to make stealing your account easy;
2) Do not randomly pick a pre-fix and post a WTB. The reason you do not see a WTB pre-fix in your menu is that either you are using the wrong forum to post or your EE account does not have that privilege yet. We will just delete these WTB ads using wrong prefix in the wrong place;
3) Very basic principle. Do not try to bump or repost an item in any way or in any form in less than 7 days. No matter how you re-word it, re-jig it or re-price it, it is considered to be a "cheating bump" by the forum and it carries a hefty penalty. Your item should only go back to the top every 7 days. Be considerate, there are others ads created by other people that need exposure;
4) Your item should only exist in one single ad entry inside all the EE forums. You should not find the your item in more than one ad entry. If your ad is getting old, bump it. Do not start a new one. Other people do not need to see your item multiple times, once is enough.
