This is NOT a scam accusation and there are no rules broken (as far as I know) because there are no rules against multiple accounts but I just find it quite weird.  There is a group of 6 or 7 accounts in Digital Goods and sub-section Accounts & Invites that have 60-70+- posts and are selling very similar things.  And of those 60-70+- posts maybe half of them are from the OP and 95% of the rest are first time 1 post newbies writing loving and beautiful prose extolling how wonderful the OP is.    I know at least 2 of them are alts of each other because 99% of the time they are logged in at the same moment and the rest ... who knows.  Never checked time stamps.

These 2 are the longest and 99.00% of the time logged in together. Reading the threads and beautiful vouch post prose are quite entertaining:

arikochipin  https://bitcointalk.org/index.php?topic=5220899.0  (he's the most entertaining)
Danny Lance   https://bitcointalk.org/index.php?topic=5230825.0


Then there is:

Google Ads https://bitcointalk.org/index.php?topic=5234139.0 (obvious alt of arikochipin since he replied in this topic from wrong account and email is the same)  https://archive.vn/OC5C8
Litvak500 https://bitcointalk.org/index.php?topic=5250792.0 (virtually identical text in OP as Google Ads aka arikochipin)  https://archive.vn/TUMOs

There's a bunch of others all similar topics just like those except they often delete their last couple posts so their threads fall way back  then they suddenly add a new post and back they are. These couple are still on top.
