The original source is much better written and explains the core of what the paper actually uncovers:
> [...] found a vulnerability in the algorithm that decides Twitter Trending Topics: it does not take deletions into account. This allows attackers to push the trends they want to the top of Twitter Trends despite deleting their tweets which contain the candidate trend shortly afterwards.
