There is no specific topic on bitcointalk forum, but there are bunch of accounts who are shilling and bumping https://www.koinal.io/ on the forum. They are mostly active in topics with content like "where to invest" "what to buy" "what to hold" and etc.

Some of these shillers/bumpers:
SDKmaster
Lunafox
Bertyda

And I'm sure there are more accounts promoting this koinal.io, who tries to look or sound like https://www.coinall.com/ or https://www.coineal.com/ exchanges.

Not to make this post off-topic, these guys are frequent posters in [ANN] QUASA OPEN LOGISTICS BLOCKCHAIN PLATFORM - topic bumped with newbies. Some of these bumping accounts were already spotted in Moss.earth topic
