How to Cloak Maxbounty link?

I'm trying to change my Maxbounty link into something nicer, Bit.ly or goo.gl doesn't work. I've had to buy a new domain and redirect but I was wondering if something knows how to mask the long link without having to buy a domain each time.

If typical link shortening services are getting flagged, there are some TLD's that are free to register.

For example, you can register .tk, .ml, .ga, .cf and .gq extension domains for free via Freenom.

I can provide you unlimited blogspot domains which will not be recognised by any network, Not even fb or IG with it's linkshim algorithm. PM me for it.
P.S- Not for free
