WOT users only need to do a small bit of research to find this comment is completely unsubstantiated. "SingaporeSling" has made only two comments on WOT: one brandishing Wikivoyage as a clone, and one saying how amazing Wikitravel is- a clear conflict of interest.
In response:
1. Wikivoyage administrators have a number of policies in place to ensure the community functions well. All users are welcome to voice their opinion and we never delete comments. At Wikitravel, censorship is rampant and the paid employees of IB delete any sign of discontent or requests for technical assistance.
2. Wikivoyage receives more edits on average than Wikitravel, and has a larger contributor base backed up by Wikipedia. This equates to more up-to-date content and better written guides overall.
