A good idea in theory Spiritoi, but i have seen this kind of thing on other forums and it just promotes the practice of one word responses ('Thanks' or 'Tx' or even just 'T' !) that then clogs up the threads.
I wish there was a solution to this kind of thing, but i don't think there is. I think the best thing people can do is label your work, like Bigcummer has done, perhaps even with 'facialforum.net' too so at least it is obvious where the shots come from if they get re-posted. I know i might be opening a can of worms here, but FF is full of shots that have themselves been nicked from other amateur forums and sites, Newbienudes, Domywife etc etc, and often the original posters of those shots do not want them re-posted either. If we as a forum are prepared to get on our high horses about re-posting then shouldn't we respect the other forums out there too? Obviously if this did happen, then there would be a lot less of the stuff that makes this forum great...
I think re-posting is always going to happen. If people post here they should be prepared for it, unfortunately. It is annoying and sad, but i can't see a way around it. The worst is when i see the free content that FF members have graciously given us end up on pay sites - now that IS cheeky!
edit:
And i just caught this thread - a couple who post on domywife who i know do not want to post on FF (i have tried inviting them over here in the past!)
