Cello question...

Alright now that I have your attention I have a cello question but it's not the typical on/off thread...

The last cello thread I read a few people commented on stripping down their Anejo's for fear of mold. Why is this more of a concern with them as opposed to any other cigar? Is this something I should be concerned with on other cigars as well?

Thank you for your help in advance.
