The film has since been taken down, as has her Instagram account. 

【翻译】自那以后，这部电影被下架了，她的“社交媒体” 账户也被删除了。

as 引导的这种比较结构，经常用于倒装。意思等于 and so has her Instagram account（...也是如此。）以下3 句意思相同：

The film has since been taken down, as has her Instagram account. 

The film has since been taken down, as her Instagram account has.

The film has since been taken down, and so has her Instagram account.

又如：

(1) They go to concerts frequently, as do I. （= as I do. = and so do I.）

可以译为：他们经常去听音乐会，我也是。

也可译为：他们和我一样，经常去听音乐会。

(2) She’s unusually tall, as are both her parents.  （= as both her parents are. = and so are both her parents. ）

可以译为：她特别高，她父母也都那么高。

也可译为：像她父母那样，她长得特别高。
