Google updated a safebrowsing software and a number of large sites are now experiencing the same problems as Bulbapedia, such as twitpic. However, if you have an account and login, all of the ads go away and the site will be fine. Logged in users do not see any ads.
As for lists of errors and additional set promos,
if you are talking about this sort of thing, there isn't as good of a list anywhere else online for any sets. Those are something I personally researched, developed, and keep up to date BECAUSE there wasn't anything else online like them.
We apologize for the inconvenience. Everything will be fine eventually.
