Does anyone have any advice how to build up listens and followers on Mixcloud ?

Joining the forum inspired me to post more mixes online but have pretty much only posted 1 mix in the past 2 years which was earlier this March (yes that's my fault!)... It showed listeners were down from the previous usual 2-6k to around 300.

I guess there's always the "spam FB" way but I'm not sure if that really works.

(assume that I have no money, but yes targeted ads on Facebook could work, and may be of benefit to others in the same situation )

PS. I won't pay for listens or followers so please don't suggest that.
