There used to be a lot of this on the forum early last year. Sal fixed it then it happened again the he fixed it, rinse, wash, repeat. I'm sure he'll take care of it. Maybe send him a PM so he knows it's back.
Umm for me this is nothing new it's been this way from day one joining the Viglink plugin for the forum that automatically changes keywords into links seems to be more spam than good on my phone I never click them on my computer I hover over it and it says "Link added by Viglink" and in that case I don't bother clicking it. When I first joined and it was happening on my phone I even posted about it and was told it was me or my phone was infected which I thought was hilarious because I'm in the IT industry and know better then believe that load of BS LOL
