Be careful with newbie accounts want to hire you. Be more careful with woke-up newbie want to hire you.
Users with high ranks on the forum can also scam you, there have been cases previously were users with a high rank either defaulted on a loan, or used donated funds for private purposes, etc, so basically don't trust (irrespective of ranks), but verify.
Business brands who launch signature campaigns on the forum start with brand new accounts, then they hire signature campaign managers that launch their campaigns, whilst they mostly write the Ann thread themselves. There's nothing wrong if a newbie account wants to hire you, just don't trust by clicking random links, or throwing away your privacy, just be open and professional about it all; and if they are scammers, it wouldn't take you long to notice.
