I could be well off the mark, but I got a suspicious feeling that grew the more I read. To lay it out as I saw it...
1) This negative review against 5 glowing positives. Comments are brief, but polar opposite to other reviewers. Fair enough, maybe he has higher standards lets check his other reviews...
2) Majority (but not all) are negative/neutral, ok so probably he has high standards. Reviewed them to see what he and others have said. Sometimes he goes against the flow of common opinion, not always, nothing wrong there either. But there is another trend...
3) The all of the negatives are North London and surrounds. The majority of the Positives are based abit further afield mostly Central London...
4) Aalesha's profile currently says Fulham, but usually appears to operate around Mill Hill in North London, a stones throw from Wembley and the other Negs. That profile was created in March 2018 around the same time as Ron first started posting, 9 of the 12 reviews within the 2 month window culminating in the first positive for Aalesha on April 6th.
5) Not read all his other posts, but a quick scan suggests that where they are not related to his reviews mostly they are negative comments about other WGs.
6) Finally, Aalesha has been caught doing this before, namely as Dan94. A name as innocuous sounding, and forgetable as Ron89?
I admit I could be jumping to the wrong conclusions, there's alot of subjective deductions there. But it made sense to me, has all the hall marks of a bit of devious touting and a little competition bashing. So instead of reporting I thought I'd make a little fishing post and see what reactions I got.
His response doesn't really reveal anything. If anyone can fault my reasoning, or "vouch" for Ron89, please do put me straight.
