Hi,
Well, there are two different aspects for me, first the 0iframes added by the PO themselves and even if they fix because they got caught, I still add them to the list, the second aspect being the codes like stelaartois or dodgenitro which are not added to the site by the PO but by a third party, if it is fixed before we had time to add their site to the list, I don't add them either.
The first list about 0iframes in sites is imho important so the memers know more about the site they wanted to join or are members of, there is a link to the threads where the sites are reported in the list and by reading the reports and the reactions or non reactions from the PO, it helps understanding if the addition of 0iframes to the site is a result of a honest mistake, lack of information or if it is an attempt to cheat.
The second list with 0iframes in personal pages can help everyone avoiding those sites and as some refID come up multple times, POs can know in advance that if an advertiser wants to advertise one of those personal pages, the risk of addition of 0iframe during the campaign is high.
The next list is for the virus/exploits which are not the POs fault, however like said above, some sites are fixed more quickly than others and some sites are more subject to the problem than others.
If the problem is fixed before the site is even added to the list, I won't add it either, however I know some people who won't touch a site listed in that alphabetical list which is because they think it still can harm their computer and sometimes the problem have been fixed ages ago. It is more for this list that I would like the mention of the problem being fixed and then if the problem arises again, we will report it again, unlike the other lists where we don't report the same thing each time as it is posting duplicate reports about the same problem, here it is reporting the problem having started again afr the fix.
I hope I make some sense, not feeling 100%
