SSP is short for Shameless Self Promotion.
As per IndiForum rules, people are supposed to not promote their blog/blog links on the forum. There are designated places like IndiVine, IndiSpire where IndiBlogger has made proper arrangement for people to share their latest posts, but not on the main forum. Though, you can share useful links on current discussions, if, you feel it adds value to the discussion or helps resolve a problem/issue. However, what you did was not right, as, though you didn't share a link, you dug out a long dead thread and asked people to visit your IndiVine post (which, again is not allowed).
Hopefully it's now clear to you, and we can expect your co-operation in keeping the forum clean.
