Olia Lialina has addressed the issue of digital curating via her web platform Teleportacia.org, an online gallery to promote and sell net.art works. Each piece of net.art has its originality protected by a guarantee constituted by its URL, which acts as a barrier against reproducibility and/or forgery. Lialina claimed that this allowed the buyer of the piece to own it as they wished: controlling the location address as a means of controlling access to the piece. This attempt at giving net.art an economic identity and a legitimation within the art world was questioned even within the net.art sphere, though the project was often understood as a satire. On the other hand, Teo Spiller really sold a web art project Megatronix to Ljubljana Municipal Museum in May 1999, calling the whole project of selling the net.art.trade.
