I know that if our posts get deleted by the mods and there are many of them, it means that we are making low value posts, they are being reported and eventually getting deleted. In some cases, we may get tagged by the DT members for being a shit poster.
Yes this is quite true. Actmyname tagged many members for their spamming and could be check easily in the bpip history that how much posts deleted by mod. Some other DT also tagged which looking so bad and compaign manager think twice when select members for review and signature.
Anyhow I want to know that if we delete our posts ourselves, does it have a bad effect on our account and can we still get tagged or something or it is completely normal ?
Deleting a post doesn't affect your account , however if your deleted post contain some suspicious activity then it's possible that you may recieve neutrel tag. This tag serve as a reminder and doesn't harm your account. anyway deleting post is not good practice unless you have made any mistake.
