Does science practice censorship?
Science is generally defined by how it makes discoveries and incorporates them into the body of scientific knowledge. We overlook what science excludes from it's body of knowledge.

On the positive side, science operates by making hypotheses, testing them and ultimately subjecting them to peer review. That which survives peer review is legitimate science. That which fails or avoids the process is excluded.

The cost of excluding "rumor" from science is occasional rejection of useful findings. Hypotheses which lead to productive research are unlikely to be excluded for long.
