Complete Review:
I received 50 tweets a few weeks back. Here is what i can tell you:
Pros:
1. Service was quick and OP responsive. Nice TAT no issues here
2. Tweets are on accounts with a variety of DA's averaging around mid 50's. A couple were in the mid/high 70's
3. The backlink structure of the accounts were pretty diverse from account to account. What I liked most is that each URL was unique and I had to smile a few times on how he got the links on the account. Smart little method.
4. Tweets themselves were diverse and used similar related words. The read wasn't perfect but all terms used were highly related and to the bots eyes it would all be good. No repeats, nice job.
Cons:
1. Some of the links to the twitter accounts were not showing any more. Didn't change the DA ranking, but it does matter to big G most likely, and perhaps to Moz over time. Still, a lot where showing and the way the method was done they will be there for eternity.
2. Accounts are new and quite bland. All were made last month and have no pic, etc.
Overall:
Very professional service delivered exactly as promised. Lots of good pros, the OP found a nice little niche, and for the effort vs price worth just sending the traffic his way. The cons were not really imp., I don't see any negative things form the boring accounts in terms of value, and the links that were missing if the DA is effected were promised by the OP to be replaced. I'd recommend if your looking for some nice Twitter tweets from higher DA accounts.
