My colleague runs our tumbler (a soft lesbian slavery)with soft marketing ( no begging for reposts
). The Tumbler is about 2 years old and she has about 5,000 real followers. She spends about 1h/ day Mon to Fri on this...it is NOT huge but its real and growing. Will let you know when she hits 10 K, then I will make her to beg.
The point I am making and the answer is : It requires "hard work"! So if my math is correct about 500 hours of hard work got her 5000 followers, or about 1h to get 10. So start posting
