I do not see that this is needed. Wearing a signature is not a problem instead the real problem is the posting habit that you have stated which is spamming.
OP do you really know what SPAM is all about?
Google said that spam is an irrelevant or inappropriate messages sent on the Internet to a large number of recipients.
So, spamming has nothing to do with wearing signature. You can wear signature and could avoid spamming.
In my opinion, the problem here that cause a lot of lower ranks to be less likely to get merit are those threads started to attract merit like this as an example. This one has even notice you.
This thread is a merit-seeking one, and your grammar is so bad that the OP was excruciating to read.
Stay low for now you were still a newbie and yet to become a jr. member or even rank up to member in the near future. There will be a time to get merit/s just wait and be patience even if we are not a good poster OP. One day we will be able to share knowledge and learning basing on the experience we have in this forum and when that time comes we will have greater chance on getting it.
