OP here. I posted the best information I knew about tombola at the time, following plenty of research.

Of course, you should always do your own research, especially in crypto or any volatile market. 

So they changed their blockchain. That doesn't mean, however, that the ICO is bad.  It just means they've chosen to take a different track on the tech.

As for any questions about the math and estimates in the white paper, you really should do the math for yourself and I urge you to contact the team directly on their site and social channels. 

All I was doing was sharing what I knew about an ICO that I thought the community would appreciate. And I think if you score it, you'll find that overall, the post and info in it are transparent and honest, and those are elements which far outweigh little technical details.

Dear cryptoenthusiasts

I took part on Tombola bounty campaign https://bitcointalk.org/index.php?topic=4837302.0

The task consisted of posting 10 messages weekly in Tombola's bitcointalk ANN.
It was named as "ANN moderation", we were told to leave positive comments regarding the project. Sounded strange to me, but I looked in the most common rating sites and assumed the project was legit and wasnt promoting a scam.
I saw high rating in ICObench and KYC passed, was enough for me.
#1 mistake: always do my own research

Now i have been looking deeper, looking at the previous messages in bitcointalk ANN and this seems very fishy. Seem they really changed the concept of the project, AFTER raising some funds, and that is why they were asking for positive comments.. to cover the bad comments from harmed investors!
They also did dupplicated payments to bounty members after bounty campaign ended, which would make me very angry if i were an investor, as price of token is diluted.
I also realized now that the message of bounty thread was edited.
Where it appears "You can help the team explain to other users how Tombala works".. and i can promise for my babys life, this is very different of what was stated previously as task( something sumarized as: " post positive comments about Tombola").
I am already dissapointed with myself as i think that i was helping this team raising money by not being honest to people. I promise i regret it very much and hope you havent invested a cent on this.

i checked the balance.s.and seems 94% concentrated in few accounts... this seems strange!

I also hope investors accept  my apologies (+ also for my bad english).



Sorry for the long message and best regards
