Here's my review of a small test campaign. I had originally planned to use his service for a much larger campaign but based on results that won't happen:
Bought aprox 1,500 mentions in quotes ($50).
Targets were people that had liked recent posts in a certain niche (non-adult). Seller delivered the quotes according to Twitter Stats on re-shares, but results were underwhelming.
Now 2 days later, out of 1,500 mentions, the tweet has:
14 total engagements. 1 Profile visit. 3 Link clicks.
Out of which I'm probably responsible for most myself.
I asked that seller would do a new Mention in quote, with one of my own Twitter accounts included. The result was, the account never recieved a notification of having been quoted/mentioned.
I'm guessing the majority of the bot accounts have already been blocked by twitter for spam and any tagged people won't get notified.
Asked for a refund, seller didn't want to. Rather we went into a heated argument about the "view counter" and he didn't want to accept that it's a total view counter, not a unique view counter. Told him everytime u refresh the page/post, it will count and add a new view. Didn't want to listen. Then he sends me a link to twitter FAQ that literally proves me right and still tries to argue.
What a waste of $50. You live and learn. Can' definitely not recommend. Just happy I did a test campaign first before spending $1500
