Once I encounter that kind of scams project almost 3 months advertising their campaign they are not making their start of the pre sale that's why I ask the manager if they still active then I ask a that I can't stay for long to those kind of campaign even the spreadsheet didn't update and most of the participants are asking if the campaign is alive or dead no one is answering then if that kind of campaign you will encounter you must better to leave you will just waste your time in advertising them.
